Switching Properties of the Contact Coatings Based on Refractory Metals Alloys
نویسندگان
چکیده
Switching the properties of Ag contact groups an electromagnetic relay with electrodeposited Ni-W and Co-W alloy coatings was studied. It is shown that these are able to stabilize spread resistance within entire test interval increase service life from 2.3 × 106 4.5 commutation cycles. According our research, coated mainly determined by a change in surface morphology caused electrical erosive transfer materials lesser extent formation poorly conductive adsorbed hydrocarbon films.
