NiTi合金的穴蚀试验研究

STUDY ON THE TEST OF NiTi ALLOY ON CAVITATION RESISTANCE

桨叶材料穴蚀的定量研究是个难题 ,本文选用 Ni Ti镀层作材料 。

Quantitative analysis of cavitation test about p addle materials is very difficult..By using magnetism flex stimulating cavitation trial engine,TiNi spra ying layer and heat-treated TiNi spraying layer are tested and compared.Results show that the c avitation resistance ability of the heat-treated TiNi spraying layer is better than that o f the unheat-treated TiNi spraying layer.
