This paper have analysed the resultant of the testing of friction and wear for chemical deposited layer of nickel-phosphorous alloys. Investigation shows that technique of surface treatment possess lower coefficient of friction and higher wear resisting property, higher hardness, in addition to lower deposited treating tempera ture, without deformation also non-effective about original roughness and accuracy of parts. Thut as a finished surface treating process of parts are very good, Finally, from loss weights of specimens due to wear the coefficient of wear and decreasing thickness quantity due to wear are calculated for the reference of the design of wear durability.
