What you need to know about thermocouple of vacuum furnace

Vacuum heat treatment technology has the outstanding advantages of no oxidation, no decarburization, good surface quality, etc. The workpiece after heat treatment has made great progress in wear resistance, corrosion resistance, etc. Vacuum heat treatment technology has been widely used in the tr...

Molybdenum and Molybdenum Alloy Vacuum Sintering Process

Molybdenum and molybdenum alloy metal blanks are usually prepared by powder metallurgy process. After molybdenum and its alloy powders are formed by pressure, they must be sintered at high temperature and vacuum to have metallization characteristics such as low impurities, high density and high ...

Low temperature vacuum hot pressing sintering of aluminum nitride ceramics

Aluminum nitride (AIN) ceramics have excellent comprehensive properties and are ideal candidates for high-density electronic substrates and packaging, as well as high-temperature structural materials. They also have broad application prospects in the fields of acoustics and optoelectronics. Howev...

What needs to be done for heat treatment with vacuum oil quenching furnace?

Oxidation corrosion is one of the fatal defects for product parts. Many companies use salt furnace quenching for heat treatment of product parts. When the rainy season comes every year, the parts must be surface treated within one week, otherwise the residual salt will corrode the parts, leading ...

Pressureless Sintering of Silicon Carbide Ceramics

Silicon carbide is a strongly covalently bonded compound, therefore, the diffusion rate during sintering is rather low. Silicon carbide is difficult to sinter. Densification must be achieved with the aid of additives or external pressure or reaction. The high cost of silicon ceramics has seriousl...

Micro-alloyed vacuum carburized gear steel

The common feature of the new gear steel is that it is micro-alloyed and used after vacuum carburizing, so that resources and energy can be saved in the production process of gears, and it has high performance during use. 1 High temperature carburizing gear steel Experiments show that in order t...

What should we do when problems occur in vacuum heat treatment?

First of all, vacuum heat treatment technology is a very widely used technology, which is widely used in aerospace, electronics and precision machinery. In the production of mold, it has outstanding advantages that ordinary heat treatment cannot compare with, because vacuum heat treatment has the...

High temperature vacuum carburizing gear steel

When the gear carburizing temperature is increased from 930 ℃ to 1 000 ℃, the carburizing time can be shortened by more than 50%, and the production efficiency can be significantly improved. However, the austenite grains tend to grow during high temperature carburization of commonly used gear st...

Gear vacuum carburizing process

Agricultural vehicles and tractor transmission gears are generally made of 20CrMnTi low carbon alloy steel. Because agricultural vehicles and tractors mostly drive on country roads, fields and poor road conditions, high strength, high wear resistance, high hardness, high impact toughness, and hi...

Vacuum heat treatment of steel ring

GCr15SiMn steel ring is a kind of wear-resistant accessory on concrete pump truck. Because it has been in contact with wet cement sand and gravel particles such as concrete for a long time during operation, is worn by abrasive particles and eroded and corroded by concrete slurry, and the service ...
