What is Cobaltalloy powder used for (marketing department of Shanghai HY Industry Co., Ltd)
Cobalt alloy powder, is a kind of hard alloy that can resist various types of wear and corrosion as well as high temperature oxidation.
Cobalt-based high-temperature alloy lacks the reinforcing phase of the common lattice, although the medium-temperature strength is low (only 50-75% of the nickel-based alloy), but in higher than 980 ℃ has a high strength, good resistance to thermal fatigue, thermal corrosion and wear corrosion resistance, and has good weldability. Suitable for the production of aviation jet engines, industrial gas turbines, naval gas turbine guide vanes and nozzle guide vane and diesel engine nozzle, etc.
Stellite alloy is a class of alloy with cobalt as the main component, containing a considerable amount of nickel, chromium, tungsten and a small amount of molybdenum, niobium, tantalum, titanium, lanthanum and other alloying elements, and occasionally also contains iron. Depending on the composition of the alloy, they can be made into welding wire, powder for hard surface surfacing, thermal spraying, spray welding and other processes, as well as cast and forged parts and powder metallurgy parts.
Cobalt alloy powder
Pre-alloy powder manufacturing method is divided into atomization method, wet metallurgy method. Pre-alloy powder high-pressure atomization method is designed in accordance with the ratio of the carcass, in advance of the sintering of various components of the metal melted into an alloy, and then atomized spray powder, the required particle size of the carcass powder. Atomization method can use water atomization or gas atomization, gas atomization available air, nitrogen or argon and other gases. Gas atomization cooling speed, fine powder grain, high powder yield, low cost.
Powder metallurgy technology integrates material preparation and parts forming, and is an advanced manufacturing method for automobile manufacturing, machining, new energy development and utilization, and aerospace materials, which plays a great role in energy saving, metal saving, strategic materials saving, labor productivity improvement and environmental protection.
