Research On Wear And Corrosion Resistance Of Ceramic Powder Modified Phenolic Resin

Friction consumed one-third of one-off energy in the world.Nearly 80%accessories failed for wear damage.What is more,50%of mechanized equipment incident were caused by the lubrication failure and excessive wear damage.So study on the wear resistance and lubrication behavior of coating would benefit the social economic.The coating used phenolic resin as matrix adulterated with Al2O3,SiO2,plasma modified SiO2 as reinforcement phase respectively,while MoS2 and PTFE was added respectively into phenolic resin as lubricious filler.MS-T3000 wear and friction tester and MFT-4000 multifunctional surface tester were used to characterize the friction coefficient,wear damage with different load,rotary speed respectively(500g,1000g,200r/min,400r/min).The optical microscope and scan electron microscope were taken to observe the profile of damaged coating.The tensile test machine indicated the shear strength of coating which mixed with different fillers.There were the conclusion of this paper:1.The shear strength of the coating adulterated with reinforcement is much higher than that of lubricious filler.The coating have a considerable enhance in shear strength when plasma modified SiO2 added less than 15%.2.Lubricious stuff attributes to lower the friction coefficient.The phenolic resin coat has a excessive low friction coefficient with different volume PTFE added.But the coat gets a minimum friction when 11%MoS2 involved.3.The wear resistance originated from lowering the friction works more efficiency than strengthening the coat to alleviate wear damage.4.The comprehensive properties of coat added with plasma modified SiO2 is inferior to the one with raw SiO2.While the plasma modified SiO2 ones strengthened considerable in wear resistance at high rotary speed and heavy load(400r/min and 1000g)5.The lyophobic filler including MoS2,PTFE,plasma modified SiO2 also attribute to the anti-erosion of the coat.The addition is 11%for MoS2,25%for PTFE,25%for plasma modified SiO2 respectively are considerable helpful to anti-erosion property.
