In order to improve the strength and wear resistance of powder metallurgy gears, we usually need to add post-processing engineering after the powder metallurgy gears are sintered to improve their performance. For example, in the post-treatment of powder metallurgy gears, engineers of powder metallurgy gear manufacturers generally use surface water vapor treatment and carburizing treatment to increase the wear…
The main purpose of surface treatment of powder metallurgy parts: Improve wear resistance Improve corrosion resistance Improve fatigue strength The surface treatment methods applied to powder metallurgy parts can basically be divided into the following five categories: Coating: Cover the surface of the processed part with a layer of other materials without any chemical reaction Surface chemical treatment:…
P/M offers designers and users a versatile and efficient method of producing parts and components. The process is versatile because it is applicable for simple as well as complex shapes, and a full range of chemical, physical and mechanical properties are achievable. The process is efficient because it produces moderate to high volume net or near-net shapes, with almost…
Powdered metal gears are made through the process of powder metallurgy. There have been many advances to this process over the years, which have in turn caused an increase in the popularity of powdered metal as a gear material. Powdered metal gears are used in many industries, but are used most in the automotive sector. Typical automotive applications include…
What’s is powder metallurgy bearing? Powder metallurgy bearings are made of metal powder and other anti-friction material powders pressed, sintered, shaped and oil-impregnated. They have a porous structure. After being soaked in hot oil, the pores are filled with lubricating oil. The suction effect and frictional heating cause the metal and oil to expand by heating, squeezing the oil…
Sintering is a heat treatment applied to a powder compact in order to impart strength and integrity. The temperature used for sintering is below the melting point of the major constituent of the Powder Metallurgy material. After compaction, neighbouring powder particles are held together by cold welds, which give the compact sufficient “green strength” to be handled. At sintering…
COVID-19’s impact on the automotive supply chain may be substantial. Countries that have been heavily impacted by the outbreak, in particular, China, Japan and South Korea, account for a significant share of global auto manufacturing. China’s Hubei province, the pandemic’s epicenter, is one of the country’s key automotive production centers.Especially many powder metallurgy OEM auto parts supply chain are…
The Sustainability Role of Powder Metallurgy For many years, powder metallurgy has been delivering sustainable value as an industry. We have just not defined ourselves or compared our products and processes to competing metal-forming process alternatives in those terms. The balance of this discussion will compare and contrast PM’s sustainable value with other metal forming processes. Addressing manufacturing processes,…
Flexibility The powdered metal parts process provides unparalleled flexibility in the design of complex net shape or near-net shape parts with unique mechanical properties. Consistency Consistent dimensions from part to part, order to order, year to year. Precision Dimension accuracy is controlled throughout the production process. Tolerances can be held within 0.001 in. (0.025 mm) Versatility The design engineer…
Aero-engine and land-based gas turbine applications Aero-engine and land-based gas turbine applications for Powder Metallurgy products require extremely good properties and the PM-based process routes in this sector generally incorporate Hot Isostatic Pressing (HIP). For nickel-based superalloy turbine discs, processing from powders has become necessary to allow the next increments in product performance, through enhanced microstructural control and compositional…
