Surface treatment is a process of artificially forming a surface layer on the surface of a matrix material that has different mechanical, physical, and chemical properties from the matrix.

China's powder metallurgy standardization work adhere to the enterprise as the main body, market-oriented, in order to serve the development of non-ferrous metal industry as the focus, successively formulated and revised a large number of more effective, more adaptable to the market of powder metallurgy national standards and industry standards.

In the world of power electronics, the Insulated Gate Bipolar Transistor (IGBT) plays a vital role. It combines the advantages of both the Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) and the Bipolar Junction Transistor (BJT). This article aims to provide a comprehensive understanding of IGBT and its essential functions in various applications.

Selecting raw materials: Choosing suitable metal powders and additives is important, especially when producing high-strength, high-temperature, and highly corrosion-resistant metal products, it is necessary to select raw materials with high purity and low impurities.

Powder metallurgy has three major surface anti-rust treatment methods to help products rust . The process of powder metallurgy is a very magical process and technology. Through the process of powder metallurgy, metal materials

Reasons for powder metallurgy gears to produce pitting: 1. Gear overload: Powder metallurgy gears can experience overloading during long-term operation. 2. Gear oil shortage: During long-term operation, gears can suffer from oil shortages, leading to pitting issues.

The advantages of copper-based oil-impregnated bearings are that they are cost-effective, absorb vibration, have low noise, and do not require lubrication for long working hours.

The development trend of powder metallurgy products in the shipbuilding industry: Powder metallurgy products​ are applied to shipboard equipment, which operates in harsh conditions and has limited space for equipment replacement.
