IMPROVEMENT OF ELASTIC COUPLINGS FLEXIBLE ELEMENTS FRETTING CORROSION PROTECTION TECHNOLOGY

Abstract

The problem of elastic couplings flexible elements surfaces fretting corrosion protection is considered in the work. Advanced fretting corrosion protection technology is proposed. To increase the elastic elements fretting resistanc, the use of metal-clad lubricants based on paraffin with the addition of molybdenum disulfide powder and graphite is proposed. The rational composition of the lubricant, including graphite and molybdenum disulfide in the amount of 5 to 25 weight percent each, has been determined. The increase of fretting corrosion resistance is confirmed by a significant decrease of friction surfaces roughness parameters (Ra, Rz, Rmax). The proposed technology is low cost due to the use of simple and cheap equipment, the possibility of mechanization.
