The Tribological Property and Microstructure of Ni-Ti Coating Prepared by Electrodeposition and Heat Treatment

Table 1

Comparison of friction and wear properties of two different coatings at different loads.

Coatings	Load (N)	Average friction coefficient	Wear rate (×10^−9 mm^3/Nm)
a	0.5~4.0	0.65~0.75	3.97~4.82
b	0.5	0.14	1.23
b	1.0	0.18	1.85
b	2.0	0.24	2.56
b	4.0	0.28	3.27

Note: a refers to the as-deposited Ni-Ti coating and b refers to Ni-Ti coating after the heat treatment.
