Dry Friction and Wear Characteristics of Some Reactive Elements—Doped Niobium Carbide Coatings

The friction and wear of the silicon carbide (SiC) and hot pressed silicon nitride (Si3N4) against zirconia (Y–TZP) sliding under dry friction and room temperature conditions were investigated with pin-on-disk tribometer at sliding speed of 0.56 m·s-1 and normal load of 50 N, 80 N and 120 N, respectively. It was found that, the coefficient of friction and wear rate are dependent on the test duration as well as the normal load. Through analyzing and comparing, the wear rates of the two frictional couples both are in the 10-6 mm3 (N·m)-1. Based on the variety regulation of the wear maps, the wear mechanisms of the two couples were analyzed. Between the two couples, the friction and wear characteristics of the SiC/ZrO2 couple are better than the Si3N4/ZrO2 couple’s.

Friction And Wear Characteristics

The friction and wear characteristics of spike-tooth material (65Mn steel) of Spike-Tooth Harrow in a two-stage peanut harvester were studied in this paper. The friction and wear tests of pin and disc on 65 manganese steel were carried out on the tribometer, then the wear loss and the friction coefficient were studied. The wear loss of the pin was acquired by calculating the mass of the pin before and after the experiment using an electronic balance. According to the actual working environment of peanut spring-finger, four variable parameters are set up: load, speed, soil moisture and soil type. The friction and wear characteristics of pins were studied under different loads, speeds and different soil environments. After wearing, the worn surface of the material was observed by scanning microscope and the wear mechanism was studied. The experimental results show that the wear of the pin increases with the increase of load and decreases with the increase of rotational speed in the same rotation number. Especially in the case of the sandy soil with 20% in moisture, a maximum wear loss of the pin is achieved.
