研究了RE-Ni-W-P-SiC-PTFE复合镀层的抗氧化性。结果表明：RE-Ni-W-P-SiC-PT-FE复合镀层随着氧化温度的升高，氧化膜的重量增加，但在800℃以下氧化温度对镀层的增重不显著；800℃以上，镀层的增重迅速增加。通过对三种镀层抗氧化性能的比较可知，RE-Ni-W-P-SiC-PTFE镀层的抗氧化性不如Ni-W-P、Ni-W-P-SiC及RE-Ni-W-P-SiC三种镀层好。
Oxidation resistance of electrodeposited RE-Ni-W-P-SiC-PTFEcomposite coating is studied, and results show that oxidized film weight of RE-Ni-W-P-SiC-PTFE composited coating increases with the rise of oxidation temperature; however, oxidation temperature has a little effect on the oxidized film weight of the composite when temperature is below 800℃. On the other hand, the film weight increases greatly when the temperature is over 800℃. It is known from the comparison with other three coatings that the oxidation resistance of electrodeposited RE-Ni-W-P-SiC-PTFE composite coating is inferior to that of Ni-W-P-SiC and RE-Ni-W-P-SiC coatings.
