Micropitting Generation Mechanism for Gears
To determine the mechanism behind micropitting, we measured micropit shape occurring in surface durability test, based on the real contact area size formed by asperity interaction in surface roughness. Individual micropitting within surface roughness asperity does not exceed asperity size.

Influence of Different Textures on Machining Performance of a Milling Tool
Milling plays a significant role in the machining of aluminum alloy parts. However, in the milling process, the material easily adheres to the tip of the milling tool due to the high ductility and thermal deformation of the aluminum alloy; the machining efficiency and quality are hard to further improve.

Three sized Micropits were developed. Micropits were designed and fabricated using wet etching. MEMS fabrication consists of thin film deposition and patterned of several geometric structures. For Si substrate etching three layers SiO2/ Si3N4/ SiO2 were deposited and patterned. They were used as a mask.

A Study of Micropitting Generation Mechanism
In earlier report, the authors carried out surface durability test with carburized steel roller and carburized steel roller with shot peened by two different methods. After examination, some micropitting were observed on contact surface. In this study, we clarified the generation mechanism of micropitting by measuring the geometry of micropitting in ...
