Chemical influences during tine abrasive wear process decrease tine surface roughness. The extent of experiments and modifiacions of tine tested material structures enabled to pronounce potentially useful conclusions for the tribological practice.R. TolnaiP. Cico...
It is used to detect gradual changes to the surface that can be caused by wear of the tool. The measured value of Ra on a length represents the average roughness, so the effect of isolated peaks or valleys does not influence the results and the measured length will be close to the avera...
Tribochemistry plays a fundamental role even in conventional abrasive polishing. • Shallow polishing grooves result in ductile wear regimes for oxides and SiC. • Roughness plateaus obtained by polishing have average roughness lower than 3 nm. ...
IS-surface roughness-wear ratios were examined in ball-on- disk wear tests performed with a ruby abrasive. Lower wear ratios were observed in samples with low IS and low surface roughness. The aim of this study was to examine the abrasive wear of pearlitic rail steels with different ISand ...
It is observed that the wear rate is proportional to initial interfacial load, however the observation cannot be extrapolated beyond the loads studied in the paper. The experimental observations agree well with expectations for a system where an abrasive wear model applies. We also show that the ...
The influences of cutting speed on cutting forces,cutting tempera-ture,roughness of surface,surface microstructure,and tool wear have been studied by the experiments. 对SiC颗粒增强铝基复合材料的高速切削加工性能进行了试验分析,研究了铣削速度对铣削力、切削温度、加工表面粗糙度、表面形貌和刀具磨损的影响,...

The surface roughness has a Gaussian (random) distribution, which is created in our surfaces using an abrasive polishing method, The surface is wetting, or hydrophilic, The micro-grooves are filled with the liquid, The micro-groove is placed with a slanted angle, alpha, and that its bottom ...
By subtracting the kinematic part from the measurement curve, the stochastic surface roughness curve and its maximum height Rz″ can be obtained, which is influenced by the defects of cutting tool edge or abrasive grains, built-up edges (BUE), cracks, high frequency vibration and so on. On ...
