Wear-resistant Steel Wear Causes
Aug 31, 2018

There is currently no uniform definition of “wear”. It is generally believed that wear is a phenomenon in which the working surface material of the object is continuously destroyed or lost in relative motion. There are also many methods for the classification of wear. If divided according to the wear mechanism, it can be divided into abrasive wear, adhesive wear, corrosion wear, erosion wear, contact fatigue wear, impact wear, fretting wear and so on. In the industrial field, abrasive wear and adhesive wear account for the largest proportion of wear failure of the workpiece, and wear and tear modes such as erosion, corrosion, fatigue, and fretting are increasingly attracted to the operation of some important components. Under working conditions, several forms of wear often occur simultaneously or sequentially, and the interaction of wear and failure presents a more complicated form. Determining the type of wear and tear of the workpiece is the basis for rational selection or development of wear-resistant steel. In addition, zero and component wear is a system engineering problem, and there are many factors affecting wear, including working conditions (load, speed, motion), lubrication conditions, environmental factors (humidity, temperature, surrounding medium, etc.), material factors ( Composition, organization, mechanical properties), surface quality and physicochemical properties of parts. Each of these factors changes the amount of wear and even changes the wear mechanism. It can be seen that the material factor is only one of the factors affecting the wear of the workpiece. To improve the wear resistance of the steel, it is necessary to start the friction and wear system under the specific conditions to achieve the desired effect.
