摘要
研制的Ni60自熔合金粉末虽铁含量高(Fe≤15%),但其主要性能达到了铁含量较低(Fe<5%)的著名瑞士Castolin12496牌号水平,成为国内用量最大的自熔合金粉末牌号之一。本文介绍了Ni60自熔合金及其粉末的化学成分、物理性能、喷焊工艺性能、焊层性能和应用,并着重介绍了粒度分布对粉末的松装密度、流动性、焊层硬度的影响。
Although the Ni60 selfmelting alloy powder contains comparatively high Fe content(≤15 %),but the main properties are at the same level of famous Castolin 12496,Switzerland,which contains only <5 % Fe.Because of lower price,the Ni60 has become one of the most popular selfmelting powders in China.The chemical composition,physical properties,property for spray welding,property of welded layer and application of Ni60 and it's powder are introduced.The influence of particle size distribution on bulk density,mobility of the powder,and hardness of spray welded layer is presented.
