The microhardness of composite deposit is increased by 5.6 percent and the content of UFD in the deposit is increased effectively through the using of extrudable stirring,while the abradability is reduced by 80 percent through the adding of UFD.

• 通过添加UFD粒子；Ni-P-UFD复合镀层显微硬度可提高5.；6%25；镀层磨损率可降低近80%25。
