Beschreibung
Zusammenfassung:	The invention discloses vacuum hot-dip alloy powder which comprises the following raw materials in parts by weight: 1-2 parts of aluminum powder; the particle size D50 of the aluminum powder is 100 to 500 [mu] m, and the particle size D50 of the zinc powder is 5 to 50 [mu] m. When the vacuum hot-dip coating alloy powder is applied to vacuum hot-dip coating, zinc-aluminum alloy in a coating can be distributed in a stepped mode, the corrosion resistance can be effectively improved, and the undesirable phenomena such as peeling and falling can be prevented. 本发明公开了一种真空热镀合金粉末，包括如下重量份的原料：铝粉：1-2份；锌粉：1-5份，所述铝粉的粒度D50为100-500μm，所述锌粉的粒度D50为5-50μm。该真空热镀合金粉末应用在真空热镀上时能将镀层中的锌铝合金呈现阶梯分布，既能有效提高抗腐蚀性，又能防止起皮脱落等不良现象。
