Introduction to Vacuum Annealing

Vacuum annealing process refers to the process of slowly heating the workpiece to the specified temperature under the condition of less than one atmosphere, holding it for a period of time, and then cooling the workpiece to room temperature according to the cooling method specified in the process...

Insufficient Hardness Of Carburizing And Quenching Of 20CrMo Steel Hydraulic Cylinder

1.This paper introduces the effect of carbon concentration on the surface of 20CrMo steel on its heat treatment process performance. The carbon concentration in the carburizing process must be strictly controlled to ensure that the carbon content of the furnace atmosphere is within the set range ...

Vacuum carburizing and quenching process of 20Cr2Ni4A thin-walled ring gear

1.Structure and heat treatment requirements of thin-walled ring gear The material used in the design of the ring gear is 20Cr2Ni4A. The ring gear requires overall carburization, the depth of the carburized layer is 0.9~1.2mm, and the surface hardness is ≥60HRC. From the structural analysis of the...

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...
