Study of imitative micro pit morphology evaluation
Materials Research Express, 2023 Abstract This study examined the imitative micro pit formation of pitting corrosion on 304 stainless steel under electrochemical control in a 3.0% NaCl solution. Results demonstrated that the micro pits changed from a conical to a cap shape during growth, indicating that their evolution in shape and growth did not follow the same ...

Tribology Letters, 2021 Abstract The drive to reduce fuel consumption in transportation has encouraged the emergence of low viscosity lubricants to reduce viscous losses in the engine, drivetrain, and other components. However, viscosity reduction increases the risk of surface damage, thus motivating the development of new anti-wear (AW) additives.

Research on Evaluation Methods of Material Pitting Corrosion Based on Modal Analysis [PDF]
Cailiao Baohu, 2022 Pitting corrosion destroys the continuity of the material structure and has a great impact on the mechanical properties of the material. As the average pit depth is an important index to evaluate the degree of pitting corrosion of materials, the study of

Investigations on the Micro-Pitting and Wear Behavior of Nitrided Internal Gears [PDF]
IOP Conference Series: Materials Science and Engineering, 2021 Abstract Nitriding processes can significantly increase the load carrying capacity of gears, compared e.g. to through hardened gears. Nitrided gears are generally characterized by a thin and hard compound layer on the surface and an adjacent diffusion layer that extends deeper into the material.

Friction Characteristic Study on Flat Surface Embedded With Micro Pit [PDF]
Evergreen, 2021 Mechanical systems are always deal with wear and friction as the liability. The basic principle of the mechanical system is the surface interaction between surfaces which have a frictional force resulting in fatigue and damage to the mechanical components. Lubricant is used to minimize friction in order to solve the problem.

A novel tooth tip relief method for reducing micro-pitting of spur gears
Advances in Mechanical Engineering, 2021 Micro-pitting is a common fatigue failure mode of spur gears. To reduce it, this paper proposes a novel tooth tip relief method. Gear meshing simulation is firstly performed considering the actual contact path, showing that there are four Hertz contact ...
