How to improve the strength and durability of powder metallurgy gears is what I want to share with you next. Let’s learn about it with Zhongwei Precision’s editor.
The general term for all properties of powder. It includes: the geometric properties of the powder (particle size, specific surface, pore size and shape, etc.); the chemical properties of the powder (chemical composition, purity, oxygen content and acid insolubles, etc.); the mechanical properties of the powder (loose density, fluidity, etc.) , formability, compressibility, stacking angle and shear angle, etc.); the physical properties and surface properties of the powder (true density, gloss, wave absorption, surface activity, ze%26mdash;ta(%26ccedil;) potential and magnetic properties, etc. ). Powder properties often determine the performance of powder metallurgy products to a large extent. Geometric properties are very fundamental to the particle size and shape of the powder. Powder metallurgy can produce various metal ceramic products. Powder metallurgy near Henan
Advanced equipment for powder metallurgy research - spark plasma sintering system (SPS). The SPS device mainly includes the following parts: axial pressure device; water-cooled punch electrode; vacuum cavity; atmosphere control system (vacuum, argon); DC pulse and cooling water, displacement measurement, temperature measurement, and safety control units . SPS has similarities with hot pressing (HP), but the heating method is completely different. It is a pressure sintering method that uses on-off DC pulse current to sinter directly. The main function of on-off DC pulse current is to generate discharge plasma, discharge impact pressure, Joule heat and electric field diffusion. During the SPS sintering process, the discharge plasma generated instantaneously when the electrode is fed with a DC pulse current makes each particle inside the sintered body evenly generate Joule heat and activates the surface of the particle. Guangdong Stainless Steel Powder Metallurgy Factory Powder metallurgy can produce various metal powder sintered parts.
Powder metallurgy material: powder metallurgy porous material. Also known as porous sintered material. It is made of spherical or irregular metal or alloy powder after molding and sintering. The internal pores of the material are criss-crossed and interconnected, generally with a volume porosity of 30% to 60%, and a pore diameter of 1 to 100 microns. Good permeability, thermal conductivity and electrical conductivity, high temperature resistance, low temperature resistance, thermal shock resistance, and medium corrosion resistance. Used in the manufacture of filters, porous electrodes, fire extinguishing devices, antifreeze devices, etc. Powder metallurgy tools and mold materials. Including cemented carbide, powder metallurgy high-speed steel, etc. The latter has uniform structure, fine grains, no segregation, better toughness and wear resistance than cast high-speed steel, less heat treatment deformation, and longer service life. Blanks that can be used to manufacture cutting tools, molds and components
In order to improve the strength and durability of powder metallurgy gears, it is first necessary to increase the post-processing after sintering, so as to improve the performance of powder metallurgy gears. Post-processing projects generally come in two forms:
1. Carburizing treatment: Carburizing treatment is the same as that of ordinary machined gears. At present, the integrated treatment of carburizing and quenching is adopted for powder metallurgy gears, and the hardness range is the same as above.
2. Surface water vapor treatment: Under high temperature environment, the water vapor on the surface of the gear reacts with iron to form a dense Fe3O4 material. Fe3O4 has a high hardness, which can increase the durability and surface hardness of the powder metallurgy gear.
To sum up, it is the sharing of improving the strength and durability of powder metallurgy gears. I hope this article can help you. If you want to know more about powder metallurgy, you can leave a message to the editor or the manufacturer, and we look forward to discussing with you!
