Influence of the Size of Silicon Carbide Nanoparticles on the Abrasive Wear of Electroless Nickel Coatings. Part 2

Popis výsledku v původním jazyce

The present work represents the results of an investigation on wear and wear resistance of electroless nickel coatings with SiC nanoparticles of different sizes - 10, 45, 100, 150 and 700 nm under conditions of dry friction along the surface of firmly attached abrasive particles. The investigations on silicon carbide (SiC) nanoparticles are presented in two parts. Part 1 presents the studies concerning the effect SiC nanoparticles size of 10, 45 and 100 nm, and in the current paper - Part 2 are presented results on the effect of 150 and 700 nm SiC nanoparticles. It has been established that the size of the SiC nanoparticles in combination with thermal treatment of the coatings exert substantial influence on the micro-hardness, on the character and the magnitude of linear wear, on the wear intensiveness and on the wear resistance of the coatings. The thermal treatment leads to increase in the micro-hardness of coatings without nanoparticles and coatings with nanoparticles. The highest wear resistance and micro-hardness is manifested by nickel coatings with the smallest size of the nanoparticles - 10 nm. Upon increasing the size of the SiC nanoparticles the wear resistance and micro-hardness become decreased. It has been found out that in case of 10 nm nanoparticle size the kinetic curve of the wearing off process has linear character and the stage of co-operation of the coating is missing, which indicates high energy effectiveness of these coatings. Upon increasing the size of the SiC nanoparticles the kinetic curve acquires wave-like character with well expressed stage of gradual cooperation.
