Detection Content

Detection Purpose: Find out the cause of wear, so as to replace the unqualified components in time and reduce the loss

Detection range: All kinds of metal products

Wear is the phenomenon that wear debris is gradually separated from the surface of the object under the action of friction. Wear failure refers to the failure of mechanical parts to achieve the original design effect due to the occurrence of wear phenomenon, that is, to reach the original design level. Wear failure is a process of gradual development and gradual change, which is short for several hours and long for several years. Wear, fracture and corrosion are called three forms of metal failure analysis, and its harm is very amazing.

According to the failure mechanism of wear, wear can be divided into:

① adhesion wear;

② abrasive wear;

③ surface fatigue wear;

④ corrosion and wear.

According to the wear state of the surface of the parts, it can be further divided into:

① continuous wear;

Adhesive wear;

③ fatigue wear;

④ abrasive wear;

⑤ corrosion and wear;

⑥ fretting wear;

⑦ surface plastic flow.

In corrosive environment, corrosion and wear caused by chemical reaction or electrochemical reaction of friction surface materials are called corrosion wear, which is divided into:

Oxidation wear

Fretting wear

Hydrogen induced wear
