熔点低、熔化速度快、流动性好、润滑性好，有利于脱硫效率的提高。

Lower melting, rapid melting speed, good flow and good lubricity, which benefit for desulphuration effect.

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。

Deposition efficiencies and bonding strengths of coatings are higher in the cases of higher spray power and higher H2 flow due to the better melting condition of powders during spray process.
