Low Price High Purity Alumina Made In China

Laboratory abrasion test is an abrasion test under laboratory conditions and simulated use conditions(black aluminium oxide). This kind of test cycle is short, the cost is low, and the wear test can be repeated on a large number of samples or parts. Laboratory wear test can generally be divided into sample test and bench test(white corundum manufacturers). This method has low cost and short cycle. It is the main method of early wear test, and it is sometimes also used in factories and mines.

The factors that affect the test are easy to control and choose, and the test data is reproducible, comparable and regular, and easy to analyze and compare(green carborundum). But this kind of test must pay attention to simulation, otherwise the applicability of the test data is poor. On a special bench testing machine that simulates actual use conditions experimenting(black oxide aluminum). The chemical composition, organization, mechanical properties and surface roughness of the test material surface.


(low price high purity alumina made in china)It is widely used to study the friction and wear process(silicon carbide price), wear mechanism and the law of influencing factors of friction pairs of different materials, as well as the selection of wear-resistant materials, processes and lubricants. But special attention must be paid to the difference between the sample and the actual object, the simulation of the test conditions and the working conditions(white fused alumina price), otherwise the applicability of the test data will be poor.


It is based on the sample test to select materials that can basically meet the requirements of friction and wear performance(white corundum), and use these materials to make friction parts with the same or similar structural dimensions as the actual parts. Compared with the field test, the test cycle can be shortened, the test conditions are controllable, and the data obtained is more reliable than the sample test data(white aluminum oxide blast media). The simulation of wear test The principle of determining the test conditions is to simulate the actual wear condition. (low price high purity alumina made in china)


It has two meanings(fused alumina): one is to make the laboratory test conditions basically close to the actual use conditions of the machine parts; the other is to make the wear form obtained in the laboratory wear test consistent with the wear form under the use conditions. The shape and size of the sample have an effect on the contact form, overlap coefficient, lubrication state pressure, movement speed, wear amount, etc(glass beads supplier). The bench test is closer to the actual conditions of use.


(low price high purity alumina made in china)For low-carbon steel(white aluminum oxide), according to different test purposes and requirements, wear testers can be divided into abrasive wear testers, rapid wear testers, and friction pairs composed of fixed specimens or moving specimens are generally not suitable for inversion(arc fused alumina). The form of sliding, rolling or compound friction formed by the relative movement of the specimen has an impact on the lubrication state and the failure characteristics.


Using test The wear test is carried out under the conditions of use, and the data obtained is more authentic and desirable(white fused alumina). The maximum speed of the main shaft of the four-ball machine is 3000r/min, which drives the test ball to rotate. Changing the speed, the wear generally changes, the deformation speed of the friction material and the temperature of the contact zone also change(silicon carbide companies), and even the wear form and lubrication state will be changed.
