FIELD : machine engineering.
SUBSTANCE : ball joint comprises a housing formed of two lids, irrespective of interconnected, metallic ball stud, enclosed in a housing, the polymeric liner with metal filler granules. The material of the ball stud is made of doped EP517SH alloy, and its spherical surface by vacuum arc ion plasma deposition coated Ni-Cr-Mo-Ti rare-earth metal Gd. Thus, by using this deposition ligated together with Gd REM, on a spherical surface of the ball stud is formed an additional anti-friction coating containing a plastic based matrix metal with Ni REM Gd and particulate metal carbides Cr, Mo, W, Ti.
EFFECT : ceramic oxide, gadolinium stabilized, due to the high hardness of ceramics, to protect the spherical surface of the ball stud, thereby improve the wear resistance and to align the average contact pressure of working surfaces of the spherical pivot bearings.
