Dimple-textured surfaces of square arrays with different geometrical parameters (area
density, diameter and depth) were prepared on the surface of GCr15 steel. The friction and …

The use of lasers to fabricate micro-textures on the surface of medical implants is an
effective method to improve their bio-tribological properties. In the present study, three …

The tribological performance of artificial joints is regarded as the main factor of the lifespan
of implanted prostheses. The relationship between surface roughness and coefficient of …

Inspired by the scales on the surface of crucian carp, the biomimetic fan-shaped textures
were designed and prepared on the TC4 contact surface and filled with solid lubricant …

Purpose Gears are prone to instantaneous failure when operating under extreme conditions,
affecting the machinery's service life. With numerous types of gear meshing and complex …

The longevity of prosthetic hip implants is significantly influenced by wear. Surface textures
of various length scales can reduce the friction coefficient and wear of lubricated bearing …

There is a growing number of personal healthcare devices that are in prolonged contact with
the skin. The functionality of these products is linked to the interface formed by the contact …

ZrO2 ceramics, known for their high strength and wear resistance, are ideal for artificial
joints. This study enhanced the friction performance of these joints by fabricating textured …

CoCrMo alloys are often used in the manufacture of artificial joints in the medical field, and
their special working environment will lead to corrosion and abrasion of the surface …
