Abstract: Hardness, friction and wear characteristics of electrodeposited RE-Ni-W-P-B₄C-PTFE composite coatings were studied, and the reason for these fine characteristics was explained in respect of structure. The results show that 1) the structure of RE-Ni-W-P-B₄C-PTFE composite coatings experiences a transformation process from amorphous to mixture then to crystal as the heat-treatment temperature rises; 2) incorporating of B₄C greatly increases the hardness of the coating; 3) the wear resistance of the coating is best with heattreatment for 1hat 300℃,which is greatly superior to that of the other traditional coatings.

Key words: electrodeposited; RE-Ni-W-P-B₄C-PTFE composite coatings; structure; hardness; wearresistance
