The contact forms include point contact, line contact and surface contact(brown aluminum oxide). The motion forms include sliding, rolling, rolling, reciprocating, impact, etc. The combination of different contact forms and different motion forms can form a variety of wear test methods(emery abrasive). The surface micro roughness (surface micro or macro geometric characteristics) of materials before and after friction and wear can be measured by microscope or profilometer.(brown fused aluminum oxide wholesale suppliers united states)

The measurement methods can be divided into non-contact measurement method and contact measurement method(brown aluminium oxide). The sample of this kind of testing machine is easy to process, high speed or low speed, constant speed wear testing machine, vacuum wear testing machine, and is mostly used for the comparative test of wear performance(black silicon carbide). Ferrography, invented in the 1980s, is a new technology for separating and analyzing wear debris from lubricating oil.

(brown fused aluminum oxide wholesale suppliers united states)It is suitable for the study of bearing capacity and friction characteristics of lubricating oil and grease, as well as the friction and wear performance test of various materials(white alumina). The domestic similar model is mhk-500 ring block friction and wear tester. According to the use and operation of rolling bearing, the wear resistance test of bearing steel generally adopts Timken ring block wear tester(aluminum oxide abrasive blasting grit), four ball wear tester and counter rolling ring tester.

The size of the sample is 12.319mm × 12.319mm × 19.05mm: the outer circumference of the test ring is 152.4mm(black corundum); the test speed is 0-2000r / min; the test load is 1:10 lever load. It consists of four steel balls (12.7 mm in diameter) arranged in an equilateral tetrahedron(aluminum oxide abrasive). The lower three steel balls are fixed together by oil box, and the upper test ball is supported from bottom to top by a lever or hydraulic system, and the load is 0 ~ 12600n.(brown fused aluminum oxide wholesale suppliers united states)

In order to determine the test time, it is necessary to pay attention to the sharp changes of different materials in different wear stages under certain test conditions(pink corundum); it is possible to change the failure state by strengthening the test conditions unilaterally and shortening the test time. It has good simulation, but the sample is not easy to process(aluminum oxide grit). There are many methods to measure the actual contact area, and the coating method is commonly used in engineering.

(brown fused aluminum oxide wholesale suppliers united states)Wear particles are impacted by charged particles at high temperature and emit radiation lines of various wavelengths representing the characteristics of each element(silicon carbide abrasive). The required radiation lines are separated by appropriate spectrometer, stick slip wear testing machine, and the type and content of wear micro control are determined by comparing the measured radiation lines with the prepared calibrator(synthetic corundum). Timken ring block wear tester.
