Wear-resisting ceramic elbow and chrome alloy wear-resisting elbow also set mechanical strength and high elongation in one, easy to manufacture parts, can meet the needs of architects and structural designers.The corrosion resistance of ceramic wear - resistant elbow depends on the alloying elements contained in the steel.Chromium is the most basic element to make stainless steel stamping elbow corrosion resistance, when the steel chromium content reached about 1.2%, chromium and oxygen corrosion medium, the formation of a very thin oxide film on the steel surface (self-passivation film), can prevent further corrosion of the steel matrix.In addition to chromium, commonly used alloy elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to meet the requirements of various USES on the structure and performance of wear - resistant elbow.
Because wear is a very complex microscopic dynamic process, there are many ways to classify wear.Abrasive wear, adhesive wear, wear and wear are generally accepted as the four basic wear mechanisms.Fretting wear is often studied as a type of wear due to its particularity.
Under the actual working conditions, the wear of ceramic elbow is not only a kind of wear mechanism, but also the result of multiple wear mechanisms.Only under certain conditions can a mechanism play a major role.When the premise changes, it may change from one mechanism to another.
There are many and complex factors affecting the wear mechanism.Such as the working premise (load, speed, motion, etc.), environmental factors (temperature, humidity, medium premise, lubrication, etc.) and part of the material composition, microstructure and surface physical, chemical, mechanical function, etc., each factor of the wear-resistant ceramic bending a subtle change can change the amount of wear and wear mechanism.
