Influence of surface cleaning methods on contact materials as well as on the contact resistance of stationary and sliding electrical contacts was investigated. Two cleaning methods were studied: cleaning with fluorochlorohydrogencarbon (FCHC) and low temperature cleaning in reductive plasma. Contact materials for professional electronics were investigated. Dependence of the contact resistance on contact force was measured. All measurements were performed with a computer controlled system, constructed and developed in our laboratory.
