How to Prevent Heat Treatment Corrosion and High Temperature Oxidation Of Aluminum Alloy?
Aluminum alloy heat treatment is generally carried out in a nitrate furnace or a vacuum furnace. It often causes corrosion on the surface of the parts, and even black spots and holes appear. The corrosion forms of aluminum and aluminum alloys are mainly pitting corrosion, intergranular corrosion,...
Performance Characteristics and Uses of Industrial Pure Copper
The reserves of copper in the earth’s crust are relatively small, but copper and its alloys are the earliest metals used in human history. Historians once used copper utensils as a symbol to divide the development stage of human society-the Bronze Age. Copper and copper alloys used in moder...
Introduction of the Various Parts of the Vacuum Furnace
The vacuum furnace in the usual test if liquid exists, need a liquid evaporation process (high vacuum without heating), can gasification off the long vacuum to achieve high vacuum (other stability), if the target pressure for a long time, consider the system and Rhots pump, you can directly measu...
Common Vacuum Measurement Methods of Vacuum Furnace
1. Compression Vacuum Gauge The compression vacuum gauge is connected with a capillary closed at the top, the lower end is connected with a port of the “Y” tube, and the lower part of the “Y” tube is connected with a mercury reservoir. When in use, connect the vacuum syste...
How to Control the Formation of Quenching Cracks?
After the product is quenched and heat-treated, cracks usually form, mainly longitudinal cracks, transverse cracks (arc cracks), network cracks, and peeling cracks. The following describes how to control the formation of quenching cracks. After the product is quenched and heat-treated, cracks usu...
Plasma Nitriding Treatment of High Alloy Steel For Bearing Parts
Bearings that operate under high temperature and high speed conditions for a long time need to meet high reliability requirements. Therefore, the cleanliness of the materials used in this type of bearing is much better than that of ordinary bearing steel. This kind of clean steel can resist peeli...
Engineering Application Of Sic Ceramics
Sic ceramics have excellent high temperature strength and hardness, good oxidation and corrosion resistance, and are considered to be a wear-resistant and corrosion-resistant structural material with wide application prospects. For example, as high-temperature wear-resistant components and corros...
MIM Binder
Binders for injection molding are generally composed of binders, lubricants and plasticizers. The binder is mainly the bonding powder to keep the billet with a certain strength and thermal flow properties: the lubricant is mainly to increase the lubricity between the particles, reduce the frictio...
The Chemical Composition And Heat Treatment of Vermicular Graphite Cast Iron
Vermicular graphite cast iron is a new type of cast iron material that has developed rapidly in recent years. Because most of its graphite is worm-like with a small amount of spheroids in between, its structure and performance are between spheroidal graphite cast iron and gray cast iron, and it h...
What Are the Precautions For Aluminum Bronze Heat Treatment?
Aluminum bronze with an aluminum mass fraction of less than 7.4% is a single-phase α solid solution at all temperatures, and is often used for intermediate recrystallization annealing heat treatment after pressure processing. When the mass fraction of aluminum is 7.4%~9.4%, it is a dual-phase alu...
