What are the main wear aspects of SPA-H weathering steel plate?

SPA-H weathering steel plate 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 share of workpiece wear failure. Erosion, corrosion, fatigue, fretting and other wear failure methods are usually produced in the operation of some main components, so they are paid more and more attention.

Under the condition of working condition, several kinds of wear modes appear at the same time or successively, and the interaction of wear failure presents a more complex mode. The conclusion that the type of wear failure of workpiece is the basis for reasonable selection or development of wear-resistant steel.

Among them, the wear of parts and components is a systematic engineering problem. There are many factors affecting the wear, including working conditions (load, speed, movement method), smooth conditions, environmental factors (humidity, temperature, surrounding media, etc.), data elements (composition, arrangement, mechanical properties), surface quality of parts and physical and chemical properties, etc. The change of each element may change the wear amount or even the wear mechanism.
