Differential ring gear vacuum heat treatment
The automobile differential can make the left and right (or front and rear) drive wheels rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear carrier. The function is to make the left and right wheels roll at different speeds when th...
Advantages of vacuum sintering of cemented carbide
Vacuum Sintering: Powder sintering under sub-atmospheric pressure conditions. Mainly used for sintering active metals and refractory metals beryllium, thorium, titanium, zirconium, tantalum, niobium, etc.; sintering cemented carbide, magnetic alloys, tool steel and stainless steel; A compound th...
Vacuum heat treatment of aerospace aluminum alloy materials
Aerospace aluminum alloys mainly refer to: military aircraft, civil aircraft, spacecraft, and launch vehicles. In aircraft materials, aluminum materials account for more than 80%. Typical aerospace aluminum alloy products: pre-stretched sheet 7075, skin sheet, forgings, large integral wall panels...
Gear vacuum carbonitriding
Gas carbonitriding is a traditional heat treatment technique that was extensively studied in the 1960s and widely used in the 1970s. Due to the infiltration of nitrogen, the critical point (Ai, As) of the steel is moved down by this technology, which can appropriately reduce the quenching tempera...
Linear optical axis vacuum quenching
The linear optical axis is a product that has the guiding function of the sliding bearing and can perform linear motion. The necessary conditions required for these linear motion systems are: simple design, best execution capability, low maintenance cost, use of carefully selected durable materia...
GCr15 Bearing Steel Effect of Tempering Temperature On Microstructure and Properties
1.The quenched structure of chromium bearing steel is quenched martensite, undissolved secondary carbide and retained austenite. Among them, martensite is a supersaturated solid solution of C in a-Fe, which is a metastable phase. Supersaturated carbon atoms have a tendency to spontaneously precip...
Shaft machining vacuum heat treatment
Shaft parts act as springs for supporting and rotating parts that transmit power or motion on pre-production equipment. Vacuum heat treatment is an important step in the processing of shaft parts. This article briefly introduces the knowledge of vacuum heat treatment of shaft processing. Shaft pa...
Vacuum carburizing process of auto parts
The main purpose of carburizing heat treatment is to obtain good fatigue resistance and wear resistance of the parts, and to ensure the reliability of the performance of the parts. The heat-treated parts strengthened by carburizing and quenching include: differential gears of automobile drive axl...
Vacuum Heat Treatment of LD Steel Hexagonal Cold Heading Die
When cold die steel is working, due to the relatively large deformation resistance of the processed material, the working part of the die, especially the cutting edge, is subjected to strong friction and extrusion, so the die should have high hardness, strength and wear resistance. In addition, t...
Gear Process Vacuum Heat Treatment Furnace
Vacuum heat treatment of parts with different surface and core requirements (hard outer and inner tough): Medium carbon steel: quenching and tempering → surface quenching → low temperature tempering (surface 50~55HRC, core 265~280HBS); Low carbon steel: carburizing → quenching → low temperature t...
