Abstract

The invention discloses a material wear life prediction method, equipment and a material wear test device. The method includes setting the parameters of the test conditions; obtaining the data of the friction performance of the material in the test conditions and the failure critical hardness of the material; processing the data to obtain the change relationship of the friction performance of the material; according to the change relationship and the failure critical hardness, Calculate the wear life of the material. The device includes: a base plate; a grinding plate, which is used to rub against the sample, and the grinding plate is fixed on the base plate; a temperature control unit, used to control the temperature of the test environment; a pressure control unit, used to apply a constant pressure to the sample. Pressure; balance arm, one end of the balance arm is connected with the sample coaxial line, by adjusting the balance arm, the friction angle of the sample on the grinding plate can be changed; the drive unit is connected with the base plate, used to control the rotation speed and direction of the base plate. The invention accurately predicts the wear life of materials, and improves test efficiency and test economy.

Description

technical field [0001] The invention relates to a material wear life prediction method, equipment and material wear test device. Background technique [0002] Wear resistance refers to the ability of a material to resist wear under certain friction conditions. Wear phenomenon is very common. There are many physical, chemical and mechanical reasons for this phenomenon, mainly composed of abrasive wear, adhesive wear, fatigue wear, and corrosive wear. Wear resistance is related to almost all properties of materials, and under different wear mechanism conditions, there are different requirements for material properties in order to improve wear resistance. Many products need to be in direct contact with the user during use, or have repeated friction and contact with other objects. This repeated contact may cause the surface of the product to wear and affect the appearance of the product and even the performance of the product. Therefore, the surface of this type of product is d...
