Silicon Nitride Parts 002
In our life there are many unclear material, ceramic, in particular, although the ordinary ceramic, it is can be a lot!
Silicon nitride is a kind of important structure ceramic materials.It is a kind of super hard material, itself has the lubrication, and wear resistance, as the atomic crystal;When high temperature oxidation resistance.And it also can resist cold and hot shock, in air heated to above 1000 ℃, a sharp cooling heating sharply again, also won't fracture.It is because of silicon nitride ceramics with such excellent properties, people often use it to manufacture bearings, steam turbine blades, mechanical seal, mechanical components, such as permanent mould.
Silicon nitride ceramic to make engine parts of heating surface, can not only improve the quality of diesel engine, save fuel, but also can improve the thermal efficiency.In our country and the United States, Japan and other countries have developed this kind of diesel engine.
