Characteristics of Ceramic Corundum Wear Resistant Elbow

　Wear-resistant ceramic elbows do not corrode, pitting, erode or wear. Because of the good corrosion resistance of ceramics, the integrity of the structural component engineering design can be permanently maintained. Good integrity. Because wear-resistant ceramic elbows are double reinforced, and in some cases even multiple reinforcement measures are taken, the material properties are effectively improved. In addition, the ceramic material has a low coefficient of expansion, so its volume is not disordered and cracking is not possible, and therefore has good integrity. In addition, the construction is monolithic, without joints, and the integrity is further improved.
　　
　　Wear-resistant ceramic elbows containing chromium alloy Wear-resistant elbows also integrate mechanical strength and high ductility. It is easy to machine and fabricate parts that meet the needs of architects and structural designers. The corrosion resistance of ceramic wear elbows depends on the alloying elements contained in the steel. Chromium is the basic element for obtaining corrosion resistance in stainless steel stamped elbows. When the chromium content in steel reaches about 1.2%, chromium reacts with oxygen in the corrosive medium to form a thin oxide film (self-passivation film) on the steel surface, which prevents further corrosion of the steel substrate. In addition to chromium, commonly used alloying elements include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various applications for the structure and performance of wear-resistant elbows.
　　
　　Causes of engineering surface wear
　　
　　Since wear is a very complex micro-kinetic process, there are many ways to classify wear. The most commonly used method of classifying wear is based on the wear mechanism. The four basic wear mechanisms that are generally accepted are abrasive wear, adhesive wear, fatigue wear and erosion wear. Micro-motion wear is often studied as a wear type due to its specificity.
　　
　　Under actual working conditions, ceramic elbows are often worn not only by one mechanism, but by several mechanisms at the same time. Only under certain conditions can a certain mechanism play an important role. When the current mechanism changes, it may change from one mechanism to another.
　　
　　The factors affecting the wear mechanism are many and complex. Such as the working conditions (load, speed, mode of movement, etc.), environmental factors (temperature, humidity, media, lubrication conditions, etc.), composition of the part material, organization, and the physical, chemical and mechanical function of the working surface. Small changes in each factor of the wear-resistant ceramic elbow can change the amount of wear and the wear mechanism.
