By imitating the surface characteristics of wear-resistant organisms, the bionic non smooth surface morphologies of point, strip and mesh are

The cylinder block is the framework of the automobile engine, with thin wall and complex structure. In the casting production,

The existence of flake graphite in the middle layer of gray cast iron seriously affects the improvement of its properties.

Fatigue wear failure of gray cast iron is a phenomenon that metal is removed from the contact area under the

Since the 1990s, researchers have carried out a lot of research on the surface modification of gray cast iron, among

The results show that the laser surface biomimetic strengthening technology can effectively improve the fatigue wear resistance of gray cast

Laser surface strengthening technology is widely used because martensite, austenite, carbide and other strengthening phases occur in the machining area.

In order to make gray cast iron more widely used, the graphite morphology in gray cast iron must be strictly

According to the body surface characteristics of wear-resistant organisms, hard elements on such non smooth surfaces are often distributed in

The macroscopic fatigue defects of rolling fatigue wear are mainly formed by the propagation of fatigue microcracks. Fatigue micro cracks
