水雾化法制备镍基自熔合金粉末工艺研究
Study on the Preparation Process of Nickel-based Self-fluxing Alloy Powder by Water Atomization Method
摘要
Abstract
Nickel-based self-fluxing alloy powder was prepared via water atomization in this paper.By adjusting the atomization process parameters,including nozzle diameter,spray angle,and atomization pressure,the effects of these parameters on powder morphology,particle size distribution,and hollow particle rate were investigated.The results indicate that under optimized conditions(spray angle of 32°,atomization pressure of 12 MPa,and nozzle diameter of 6 mm),the prepared alloy powder exhibits excellent performance with a bulk density of 4.22 g/cm³,hollow particle rate of 25.8%,oxygen content of 0.032%,and fluidity of 16.5 s/50g.These characteristics meet the performance requirements for surface spray-coating applications on screws and ball valves.关键词
