Solid self-lubricating composite material physics and comprehensive mechanical property depend on matrix, and greasy property depends on self-lubricating solid agent
Tribological property.According to the difference of matrix, solid lubricating composite material is usually divided into metal-base lubricating composite material, nonmetallic
Base lubricating composite, ceramic base lubricating composite three classes.Metal-base lubricating composite material is using metal as the compound of matrix
Material, and a kind of more material of research.Its self-lubricating property depends on the analysis of the self-lubricating solid phase in friction process
Going out and Dispersed precipitate, self-lubricating agent is precipitated more, then can form transfer lubricant film, friction can be made to be happened between transfer membrane,
So as to reduce fretting wear.Currently, the application study of the high temperature heat-resistings such as Fe bases, Ni bases, Co bases, Ni-Cr bases is compared
Extensively.Such as in Ni-Cr alloy matrix, S, MoS2/WS2Addition and Cr in high temperature sintering, have cenotype CrxSyIt generates,
CrxSyIt is mostly hexagonal crystal system or monoclinic system, fusing point is higher, and after they form eutectic, fusing point can be from 1300 DEG C or so
600~900 DEG C are dropped to, and easily deformable in high temperature, Cr is formed in workpiece surfacexSyLubricating film.Non-metal base lubricates composite wood
Material has certain mechanical strength, quality is good compared with flexible toughness, vibration-absorbing denoising, chemical stabilization mainly using high molecular material as matrix
Property it is good, tribological property is protected from environmental smaller, can be used in water and the ultra-low temperature surroundings such as liquid nitrogen, liquid hydrogen under, but machinery is strong
Spend low, bearing capacity is poor, and heat-resisting and heat transfer property is undesirable.So preparing the coating material for occuping superior heat resistance performance always
It is necessary to.
