Abstract

Fly ash is a waste matter generally emitted abundantly from chimneys of the production facilities and should mostly be recycled. In this context, this study reveals the tribological effects of fly ash on brake pad components by doping the fly ash in basic brake pad matrix with various weight fractions of 30% (S30), 35% (S35) and 40% (S40) by reducing aluminum powder in the pad matrix. According to the results, as the fly ash concentration increases in the matrix, density and hardness of the structure were prone to decrease to an extent. Water immersion technique was used to determine density values and specially modified pin-on-disc tribotester was utilized to measure coefficient of friction (CF) and specific wear rate (SWR) values between brake pad samples and the cast iron rotating disc. Among prepared samples, maximum average reduction in density and hardness were observed to be by 3.97% and 10.67%, respectively. S30 depicted the minimum CF of 0.32 and maximum CF of 0.43 was performed by S40. Maximum specific wear rate was observed for S40 subtending to an increase of 8.67% from that of S30 to S40. Results showed that, though higher escalation in CF as the fly ash fraction elevates in the matrix, wear rates did not show a dramatic increase which is an indication of effectiveness of fly ash in brake pads in terms of braking performance and long term durability.

粉煤灰对刹车片摩擦磨损特性的影响
粉煤灰是生产设施烟囱中大量排放的废弃物,大多应回收利用。在此背景下,本研究通过还原垫片基体中的铝粉,将粉煤灰掺入30% (S30)、35% (S35)和40% (S40)的不同重量分数的基本刹车片基体中,揭示了粉煤灰对刹车片部件的摩擦学效应。结果表明,随着基体中粉煤灰浓度的增加,结构的密度和硬度都有一定程度的降低。采用浸水法测定刹车片试样与铸铁转盘之间的摩擦系数(CF)和比磨损率(SWR),并采用专用改进型销盘式摩擦试验机进行测定。在制备的样品中,密度和硬度的最大平均降低分别为3.97%和10.67%。S30表示最小CF为0.32,S40表示最大CF为0.43。S40的比磨损率最大,比S30提高了8.67%。结果表明,尽管随着粉煤灰含量在基质中的增加,CF也会增加,但磨损率并没有显著增加,这表明粉煤灰在刹车片中的制动性能和长期耐久性方面是有效的。
