Effects of meltingcondition and degassing processes on hydrogen content in magnesium alloy melt were investigated with a self-developed instrument for measuring hydrogen content.
利用自行开发的镁合金定量测氢仪研究了熔化条件和除气工艺对镁熔体含氢量的影响。

Deposition efficiencies and bonding strengths of coatings are higher in the cases of higher spray power and higher H2 flow due to the better meltingcondition of powders during spray process.
较高的喷涂功率和较大的氢气流量，有助于改善粉末的熔化程度，从而提高涂层的沉积效率和结合强度。
