On the wear of deposited mild steels

Journal of the Japan Welding Society, 1948
It is widely adopted in mechanical industries to heap up hard metals by arc welding when parts of machinery which are required to be errosion-resistible are produced or repaired ; but in case that these special electrodes can not be used because of economical considerations — especially to-day in Japan it is very difficult to obtain tbem, instead of ...

Verification of tribo-reduction of copper oxide in phenolic composite material through visualization of friction surface

Nihon Kikai Gakkai ronbunshu, 2018
The surface of phenolic composite material was continuously observed through borosilicate glass (BK7) during friction to verify the tribo-reduction of copper oxide (CuO) taking place at the interface. Two types of pad samples were slid against a rotating

A Micropitting Study Considering Rough Sliding and Mild Wear

Coatings, 2019
Micropitting is a typical surface contact fatigue in rolling–sliding contact. The kinematic sliding is of great significance in the initiation and progression of micropitting.

Scratch, fretting, and sliding wear of a ZrB2–hardened Zr3Al2 intermetallic–ceramic composite

Journal of Materials Research and Technology, 2023
The unlubricated wear behaviour of a very recently developed ZrB2–hardened Zr3Al2 intermetallic–ceramic composite was investigated for the first time.

Masking Effect of LPSO Structure Phase on Wear Transition in Mg₉₇Zn₁Y₂ Alloy

Metals, 2021
Room- and elevated-temperature wear tests were conducted using a pin-on-disk testing machine to study wear behavior of Mg97Zn1Y2 alloy and role of long-period-stacking-ordered (LPSO) structure phase in mild–severe wear transition (SWT). Variation of wear

Environmental effects on the wear characteristics of phenolic resin composite (Confirmation of water vapor effects and proposal of tribo-degraded gas effects)

Nihon Kikai Gakkai ronbunshu, 2016
For the purpose of clarifying the water vapor effect on brake pad wear, two experiments were performed. In the first set of experiments, wear tests were conducted using four pads under three relative humidity conditions (0.8%RH, 35%RH and 65%RH).

Prediction of micropitting damage in gear teeth contacts considering the concurrent effects of surface fatigue and mild wear

, 2018
The present paper studies the occurrence of micropitting damage in gear teeth contacts. An existing general micropitting model, which accounts for mixed lubrication conditions, stress history, and fatigue damage accumulation, is adapted here to deal with

Investigation of temperature-induced wear transition of an Mg-10Gd-1.4Y-0.4Zr alloy under non-lubricated sliding conditions

Materials Research Express, 2020
The friction and wear behavior of an Mg-10Gd-1.4Y-0.4Zr alloy were investigated in detail within a temperature range of 20 °C–200 °C in order to clarify temperature-induced mild-severe (M-S) wear transition mechanism and verify if contact surface dynamic
