[0002] Zirconia ceramics are based on zirconia and utilize a unique phase transformation toughening mechanism to significantly improve toughness. They have extremely high hardness and wear resistance several times that of ordinary ceramics, enabling them to withstand strong friction and impact. They also have excellent chemical stability, resisting the penetration of acids and alkalis. They are widely used in industrial mechanical seals, cutting tools, and electronic component manufacturing, significantly extending equipment lifespan, reducing maintenance costs, and providing strong support for the development of many industries.

[0003] The above-mentioned and existing technologies have the following defects: During the use of zirconia ceramic structural components, due to the poor thermal conductivity of zirconia ceramics, the ceramic structural components are prone to local overheating, which can easily cause uneven heating and cracking, thus shortening the service life of the ceramic structural components.

[0004] Therefore, a zirconia-reinforced wear-resistant ceramic structural component is proposed. Utility Model Content

[0007] The effects achieved by the above components are as follows: by setting up an inner heat-spreading ring, an outer heat-spreading ring, and a heat-conducting ring, heat can be effectively conducted and evenly distributed, avoiding local overheating of the ceramic sleeve, improving the stability and reliability of the ceramic sleeve in a thermal environment, and preventing the ceramic sleeve from cracking due to thermal stress concentration.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figures 1-5As shown, this utility model provides a zirconia-reinforced wear-resistant ceramic structural component, including a ceramic sleeve 1 made of zirconia ceramic. The ceramic sleeve 1 contains an outer heat-spreading ring 2, an inner heat-spreading ring 3, and a heat-conducting ring 4. The outer heat-spreading ring 2 and the inner heat-spreading ring 3 are fixedly connected to the heat-conducting ring 4. All three rings are good conductors of heat. A heat-conducting pillar 5 is fixedly connected to the surface of the heat-conducting ring 4, penetrating the ceramic sleeve 1. The heat-conducting pillar 5 is also a good conductor of heat, capable of transferring heat from the heat-conducting ring 4 to the outside. The ceramic sleeve 1 has enhanced heat dissipation capacity and accelerated heat dissipation. The outer circumferential surface of the ceramic sleeve 1 is coated with an outer crack-resistant coating 6, and the inner circumferential surface of the ceramic sleeve 1 is coated with an inner crack-resistant coating 7. Both the outer crack-resistant coating 6 and the inner crack-resistant coating 7 are titanium nitride coatings. Since the titanium nitride coating has high hardness and good crack propagation resistance, the outer crack-resistant coating 6 and the inner crack-resistant coating 7 of the titanium nitride coating material can effectively improve the crack resistance of the ceramic sleeve 1, prevent the ceramic sleeve 1 from cracking when subjected to external impact or temperature changes, and enhance the strength and durability of the ceramic sleeve 1.

[0031] The outer circumferential surface of the ceramic sleeve 1 has several outer grooves 8, which are fixedly connected to the outer crack-resistant coating 6. The inner circumferential surface of the ceramic sleeve 1 has several inner grooves 9, which are fixedly connected to the inner crack-resistant coating 7. The outer grooves 8 can increase the contact area between the outer crack-resistant coating 6 and the outer circumferential surface of the ceramic sleeve 1, thereby improving the adhesion of the outer crack-resistant coating 6. The inner grooves 9 can increase the contact area between the inner crack-resistant coating 7 and the inner circumferential surface of the ceramic sleeve 1, thereby improving the adhesion of the inner crack-resistant coating 7. Both ends of the ceramic sleeve 1 have slots 10, and the inner walls of the slots 10 are slidably connected to the slots. The surface of the slots... A protective ring 12 is fixedly installed. During the transportation of the ceramic sleeve 1, the protective ring 12 can protect the end of the ceramic sleeve 1 and prevent the end from being damaged by collision, wear and other damage. An elastic block 13 is fixedly installed on the surface of the clamping plate. The elastic block 13 abuts against the inner wall of the clamping groove 10. After the elastic block 13 is squeezed by the inner wall of the clamping groove 10, the connection between the clamping plate and the clamping groove 10 can be made tighter and more stable, preventing the clamping plate from loosening during use. A pull strap 14 is fixedly installed on the surface of the protective ring 12. When the protective sleeve needs to be used, the protective ring 12 can be easily and quickly removed with the help of the pull strap 14.

[0032] The overall working principle is as follows: The ceramic sleeve 1 is made of zirconia ceramic. Due to the toughening and wear-resistant properties of zirconia ceramic, the ceramic sleeve 1 has excellent wear resistance and can be used for a long time in high-friction and high-wear environments, extending its service life. The outer heat-spreading ring 2, the inner heat-spreading ring 3, and the heat-conducting ring 4 are all good conductors of heat, which can effectively conduct and evenly distribute heat, preventing local overheating of the ceramic sleeve 1, improving its stability and reliability in thermal environments, and preventing cracking of the ceramic sleeve 1 due to thermal stress concentration. The heat-conducting pillar 5 can transfer the heat inside the heat-conducting ring 4 to the outside, further enhancing the heat dissipation capacity of the ceramic sleeve 1, accelerating heat dissipation, and better ensuring that the working temperature of the ceramic sleeve 1 is within a suitable range, reducing the impact of excessive temperature on the performance of the ceramic sleeve 1. Because the titanium nitride coating has high hardness and good crack propagation resistance, the titanium nitride coating... The outer crack-resistant coating 6 and the inner crack-resistant coating 7 of the layer material can effectively improve the crack resistance of the ceramic sleeve 1, prevent the ceramic sleeve 1 from cracking when subjected to external impact or temperature changes, and enhance the strength and durability of the ceramic sleeve 1. The outer groove 8 can increase the contact area between the outer crack-resistant coating 6 and the outer circumferential surface of the ceramic sleeve 1, thereby improving the adhesion of the outer crack-resistant coating 6. The inner groove 9 can increase the contact area between the inner crack-resistant coating 7 and the inner circumferential surface of the ceramic sleeve 1, thereby improving the adhesion of the inner crack-resistant coating 7. During the transportation of the ceramic sleeve 1, the protective ring 12 can protect the end of the ceramic sleeve 1, preventing the end from being damaged by collision, wear and other damage. After the elastic block 13 is squeezed by the inner wall of the slot 10, it can make the connection between the card plate and the slot 10 tighter and more stable, preventing the card plate from loosening during use. When the protective sleeve needs to be used, the protective ring 12 can be easily and quickly removed with the help of the pull strap 14.
