FIELD: application of anti-friction coats on inner cylindrical surfaces of parts formed by anode-cathode micro-arc oxidation.
SUBSTANCE: workpiece and device are rotated in opposite direction. Reciprocating oscillations are imparted to device along axis of surface being treated at swing and frequency determined by the following formula: Δ=(0.05-0.2)·b, f=(0.4-1.6)(ω1-ω2), where Δ is swing of oscillations of device in axial direction, mm; f is frequency of oscillations of device, Hz; b is width of rubbing member, mm; ω1 is angular velocity of rotation of workpiece, rad/s; ω2 is angular velocity of device, rad/s. Device proposed for realization of this method has body (1) with deforming member (5) and rubbing member (6) mounted on it. Rubbing member (6) is made in form of plate embracing deforming member (5). Body (1) is made in form of hollow cylinder provided with circular threaded bore (2) at the end where elastic member (4) and deforming member (5) are secured by means of thrust washer (3). Elastic member is rigidly connected with body (1) and deforming member (5) provided with oxide heat-insulating coat on its outer surface; it is also provided with circular groove for receiving rubbing member (6). Thickness of rubbing member (6) is equal to Δ=(1.3-2.0)·δ c(D/d)·(B/b), where δ is thickness of rubbing member, mm; δc is thickness of coat being formed, mm; D is diameter of cylindrical surface being treated, mm; d is diameter of outer surface of rubbing member, mm; B is width of cylindrical surface being treated, mm; b is width of rubbing member, mm. Through slot (7) made in body (1), elastic member (4) and deforming member (5) is used for securing the rubbing member to exclude its slippage. Proposed method extends functional capabilities of application of copper-based anti-friction coat on aluminum cylindrical surfaces.
EFFECT: extended functional capabilities; reduced contact pressure in zone of treatment.
