Bionic design perspectives based on the formation mechanism of dental anti-wear function
Human teeth are the important masticatory organ and therefore are subjected to friction and wear everyday. Both the loading condition and the environment are relatively complex in the mouth, however, normally human teeth can serve in mouth all their time

Sliding wear behaviour of salt bath nitrided 316LN austenitic stainless steel
The wear behaviour of AISI 316LN austenitic stainless steel has been studied by varying the duration of nitriding. AISI 316LN steel was nitrided using salt bath nitriding which consist of a mixture of 70:30 ratio of alkaline cynates and carbonates ...

Dynamics Analysis of Spatial Parallel Mechanism with Irregular Spherical Joint Clearance
Clearances caused by machining accuracy and assembly requirements are regular, but they will be irregular due to the wear of the kinematic pairs. At present, there are few studies on wear of space kinematic pairs.

Effect of Load and Frequency on the Wear Performance of 42CrMo4 and 38MnVS6 Steels [PDF]
In order to investigate the wear performance of 42CrMo4 and 38MnVS6—two alloy steels used as piston materials, reciprocating dry friction tests on two types of alloy steel materials were conducted under different loads and frequencies, using GCr15 steel ...
