Roughnesses correlation of friction contact surfaces of the modified gas-thermal covering and metal counterbody

Work is devoted to interrelation establishment between roughnesses of contact surfaces of a wearproof powder covering and a metal counterbody at a sliding friction. As modifying additives at reception wear-proof gas-thermal coverings were used ultradisperse spinels CoAl2O4, CuAl2O4. It is shown that modify-ing additives of covering and counterbody material essentially influence correlation of roughnesses of contact surfaces of a friction.
