Abstract
In this paper, the wear test was carried on with cylinder piston by the wear test device, receiving the results of the piston ring wear and abrasive characteristics by monitoring the wear process, the thesis analysis and put forward the nano-CaCO3 lubricating oil additive anti wear mechanism by the ferrography analysis technology, and provide the technical reference for the relevant measures to reduce wear and the friction, and provide reference value for further study on the related theories of reducing wear and reducing friction.
Highlights
The Wear TestInternal combustion engine is the most important power Taking the piston-cylinder produced by a combustion machinery, which is widely used in all walks of life, such engine factory as the test object (hereinafter referred to as as aviation, railways, machinery[1].With the rapid piston-cylinder,model 4100QB).The domestic Kunlun development of production practice, the wear of internal lubricating oil was used as the lubricating condition,we combustion engines is diversified and the degree of wear can analyze the characteristics of abrasive grain and the is getting deeper and deeper. with the rapid development wear of piston in the three wear period by the of nanotechnology, nonmaterial have the characteristics of small size, large specific surface area, quantum effect, ferrography analysis technology and analyze the influence of nano-CaCO3 lubricant additive on wear from quantum tunneling effect and interface effect[2].The macroscopic and microscopic perspectives
Application of nonmaterial in tribology has become an important research topic of nanoscale tribology[3].And we can analyze the characteristics of abrasive grain by
The following figures are the fields of abrasive grains in 5μm smaller than the typical grain size without CaCO3 run-in period which under the condition of adding additive
