Oxygen ethane flame

Effect of rare earths in oxy-acetylene spray-welding coating;

稀土在氧-乙炔火焰喷焊层中的作用机理

This paper discusses the effects of rotational speed of a part on the remelting quality of coating player when surface of the part is treated by using remelting and two -step spray melting method with oxy-acetylene flame self-melting alloy powder.

本文研究对回转体零件表面进行氧乙炔焰自熔合金粉末二步法喷熔，用火焰对涂层作重熔处理时，零件的旋转速度对涂层重溶质量的影响。

The results shown that under the same working conditions, the anti-pitting life of spraying weld tappet heated by oxyacetylene flame is longer one-fold and 4-fold compared with 212 built up welding alloy tappet and tufftride Stger tappet treated with 20Cr gas respectively.

作者以45号钢为基材,对其施行表面喷焊覆层强化处理的工艺,试验研究了氧乙炔焰喷焊斯太尔挺杆与国产斯太尔凸轮配副的抗点蚀性能。

This paper analyses the shortcomings of oxyacetylene flame line-material coating technology, gives some measures to overcome them, gets the developed technological parameters by improving the ways of pretreatment and optimizing technological parameters , certifies the realizability of applicating the improved technology by cheek test.

本文分析了氧乙炔焰丝材喷涂工艺的缺点,提出了改进措施。
