Problems solved by technology

[0003] At present, the surface treatment technology at home and abroad is to carry out surface treatment on the surface of the product through electroplating, anti-rust oil treatment, spraying, etc. after the product is processed. The surface strength, hardness and corrosion resistance of the final cylinder liner have been improved, but a lot of manpower and material resources have been wasted

Embodiment 1

[0019] Such as figure 1 As shown, a new type of cylinder liner honing treatment process, the weight percentage of honing oil raw materials used in honing is: kerosene 97%, WS 2 Powder 3%. During honing, the surface of the inner hole of the cylinder liner 1 is squeezed by the honing abrasive strip 2, so that the contact force reaches 10% of the ultimate strength of the squeezed cylinder liner. Others can be carried out by referring to conventional techniques in the art, so details will not be repeated.

[0020] Such as figure 2 As shown, there is a layer of WS on the surface of the inner hole of the cylinder liner 1 obtained after honing 2 Film 3 has a thickness of about 0.6 μm.

Embodiment 2

[0022] A new type of cylinder liner honing treatment process, the weight percentage of honing oil raw materials selected for honing is: 98.5% kerosene, WS 2 Powder 1.5%. During honing, the surface of the inner hole of the cylinder liner 1 is extruded by the honing strip, so that the contact force reaches 8% of the ultimate strength of the extruded cylinder liner, and other operations can be carried out by referring to conventional techniques in the field.

[0023] Such as figure 2 As shown, there is a layer of WS on the surface of the inner hole of the cylinder liner 1 obtained after honing 2 Film 3 with a thickness of about 0.5 μm.

[0024] After testing: the cylinder liner sample treated with tungsten disulfide by the process of the present invention has a friction coefficient of 0.1319 under lubrication conditions, and a friction coefficient of 0.4759, 04800 under dry friction conditions; The friction coefficient is 0.1856 under the working condition, and the friction c...

Abstract

The invention relates to a novel air cylinder sleeve honing treatment process. Honing oil selected during honing contains WS2 powder of 1.5-3wt%. By adding a certain amount of the WS2 powder in the honing oil, surface treatment is performed in the process of honing, in other words, a highly-thin WS2 friction film (with thickness not less than 0.05 micrometer) is formed on the surface of the inner wall of an air cylinder sleeve by means of extrusion and friction, so that friction characteristics of the surface of an inner hole of the air cylinder sleeve are changed, and friction reducing performance, wear resistance and corrosion resistance are improved.

Description

[0001] technical field [0002] The invention belongs to the technical field of honing, and in particular relates to a novel cylinder liner honing process. Background technique [0003] The cylinder liner is one of the key core parts of the internal combustion engine, and it is also one of the vulnerable parts. The development of the cylinder liner industry is closely related to the development of the internal combustion engine industry. With the development of internal combustion engines in the direction of high speed, high performance, low fuel consumption, low emission, and long life, the quality and comprehensive performance of cylinder liners are bound to be higher and higher. [0004] At present, the surface treatment technology at home and abroad is to carry out surface treatment on the surface of the product through electroplating, antirust oil treatment, spraying, etc. after the product is processed, although the surface strength, hardness and corrosion resistance of...
