After putting into practice, particulate lubrication has played a positive role in grinding[1], die casting[2], assistant bearing of aeroengine[3], triple bush journal bearing, brakes[4], gearbox and bearing[5] and so on[6, 7].
Except for traditional layered structure, solid lubricant such as graphite, MoS2 and WS2[8], there is also environmentally friendly material like boron nitride and boric acid[9].

The arduous conditions of mechanical, thermal and corrosive loading lead to several materials and processing challenges where mechanical properties and metallurgical stability must be maintained in a service environment where temperatures are increasing.
In terms of materials, this has meant the development of newer alloys, e.g.
