Abstract

The invention discloses a material wear life predicting method, material wear life predicting equipment, and a material wear test apparatus. The material wear life predicting method comprises: settingtest condition parameters; obtaining the friction performance data of a material in the test condition and the failure critical hardness of the material; processing the data to obtain change relationship of the friction performance of the material; and according to the change relationship and the failure critical hardness, calculating the wear life of the material. The material wear test apparatus comprises: a base disc; a grinding sheet for rubbing against a sample and fixed on the base disc; a temperature control unit for controlling the temperature of a test environment; a pressure controlunit for applying constant pressure onto the sample; a balance arm, wherein one end of the balance arm is coaxially connected to the sample, and the friction angle of the sample on the grinding sheetis changed by adjusting the balance arm; and a drive unit connected to the base disc and used for controlling the rotation speed and the rotation direction of the base disc. With the method, the equipment and the apparatus, the wear life of the material can be accurately predicted, and test efficiency and the test economy can be improved.

Description

technical field [0001] The invention relates to a material wear life prediction method, equipment and material wear test device. Background technique [0002] Wear resistance refers to the ability of a material to resist wear under certain friction conditions. Wear phenomenon is very common. There are many physical, chemical and mechanical reasons for this phenomenon, mainly composed of abrasive wear, adhesive wear, fatigue wear, and corrosive wear. Wear resistance is related to almost all properties of materials, and under different wear mechanism conditions, there are different requirements for material properties in order to improve wear resistance. Many products need to be in direct contact with the user during use, or have repeated friction and contact with other objects. This repeated contact may cause the surface of the product to wear and affect the appearance of the product and even the performance of the product. Therefore, the surface of this type of product is d...
