Friction and wear behavior of sintered antifriction materials at high sliding speeds

ZhNBM material exhibits very high wear resistance with good surface quality in unlubricated rubbing operation in air at sliding speeds of up to 50 m/sec. It can therefore be recommended as a suitable material for end-face seals intended for operation in liquid and gaseous environments. In operation without lubrication MG30ZhN1K material possesses good wear resistance only under light loads (0.1–0.2 MPa). The formation of spots which are rubbed off during operation leads to the conclusion that a plasticized film may be present in the contact zone of an end-face seal, and this substantially reduces the thermal load which the seal must withstand and prolongs its useful life.
