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...
