Questions About Powder Metallurgy
What is powder metallurgy? Powder metallurgy is a technology that manufactures metal powders and uses metal powders (sometimes with a small amount of non-metallic powder) as raw materials to manufacture materials or products through mixing, forming and sintering. It includes...
Is Cemented Carbide Tungsten Steel?
Many people think that cemented carbide is tungsten steel, but in fact, cemented carbide is not tungsten steel. Although tungsten steel is a type of cemented carbide, the two are not the same. The tungsten content of cemented carbide is...
Surface Treatment Process of Powder Metallurgy Parts
The metal injection molding process can manufacture precision parts and components with strict tolerances of ±0.025 mm and fine details. However, parts made with CNC milling machines usually have obvious marks. Therefore, surface treatment is a core part of the...
Application of Metal Materials in the Science and Technology Industry

Corrosion Resistance and Wear Resistance of Titanium Alloy
1 Surface modification technology of titanium alloyTitanium alloy has low density, high specific strength, good corrosion resistance and strong fatigue resistance. It has been widely used in aerospace, enclosure, automobile, medical and other fields. However, titanium alloy has high friction...
Effects and Defects of Powder Forging on Forging Metal
At the end of the last century, a new metal plastic forming process, powder forging, was successfully developed abroad. It has successively forged automobile differential planetary gears and connecting rod forgings, and built the first powder forging production line. It...
Nickel-Based High-Temperature Alloy Powder Preparation Technology
High-temperature alloy, also known as heat-resistant alloy or superalloy, refers to an alloy based on iron, nickel and cobalt, which can resist oxidation, corrosion and creep at high temperatures above 600°C, and can work for a long time under high...
What is a Steel-Bonded Cemented Carbide Flow Disc?
The hard phase (tungsten carbide or titanium carbide) of steel-bonded cemented carbide generally accounts for 30%-50% of the total mass of the alloy, and the rest is the steel matrix. Since the steel matrix accounts for a large proportion and...
What Alloy Materials Are Needed for Aerospace Engines？
