Soft Magnetic Materials Vacuum Heat Treatment Process
The raw materials of soft magnetic alloy are mainly bar, strip and plate, etc., and the parts are cut, punched and cut, stamped or wound in cold working way. In the process of machining, the original grain structure of the material will be destroyed, so that the magnetic conductivity of the mater...
Advantages of Plasma Nitriding Piston Rings
The surface hardness of the piston ring is improved by plasma nitriding (≥ 700HV0.1), the friction torque is small, the friction coefficient is small, the friction reduction performance is good, and the wear resistance is high, which prolongs the service life of the piston ring. The surface cryst...
Preparation Process of Multilayer Metal Composites
According to the different physical states of the member materials in the preparation process of multilayer composites, the preparation methods of multilayer composites can be roughly divided into three categories: solid-solid composite, liquid-solid composite, liquid-liquid composite composite. ...
Production Process of Stainless Steel Powder for Metal Injection Molding
Metal injection molding technology is developed from powder injection molding technology of ceramic parts, and it is a new type of powder metallurgy near-net forming technology. The main production steps of metal injection molding technology are as follows: metal powder and binder mixing – ...
Analysis of Leakage Causes of Aluminum Alloy Plate Heat Exchanger
Aluminum alloy plate heat exchanger (hereinafter referred to as heat exchanger) is a pressure vessel, and must meet the corresponding pressure requirements during its application. Due to its structural characteristics, its welding process can only be achieved by vacuum brazing. Vacuum brazing is ...
