Purpose

The purpose of this study is to deals with the effect of premixed dual metal sulfides (tin disulfide + iron disulfide) as a replacement for antimony trisulfide on the tribological performance of brake friction materials.

Design/methodology/approach

In this study, brake friction materials were developed by using premixed dual metal sulfides as a replacement for antimony trisulfide in the formulation. The brake friction materials were developed in the form of standard brake pads as per the industrial practice. Thermal stability was measured for varying ingredients and developed brake pads using thermogravimetric analysis. The physical, mechanical and thermal properties of the developed brake pads were tested as per the industrial standards. The tribological properties were analyzed using the Chase test as per SAE J661. Worn surface analysis was done using a scanning electron microscope.

Findings

The experimental results indicate that the brake pads filled with premixed dual metal sulfides had good thermal stability, physical, chemical and mechanical properties with stable friction and less wear rate due to better lubrication preventing friction undulations.

Originality/value

This paper explains the influence of premixed dual metal sulfides as a replacement for antimony trisulfide in brake pads formulation to enhance the tribological performance by preventing friction undulations.

预混双金属硫化物对无铜制动摩擦材料摩擦学性能的影响

目的

这项研究的目的是要解决预混合的双金属硫化物(二硫化锡+二硫化铁)替代三硫化锑对制动摩擦材料的摩擦学性能的影响。

设计/方法/方法

在这项研究中,通过使用预混合的双金属硫化物替代配方中的三硫化锑来开发制动摩擦材料。制动摩擦材料按照工业惯例以标准制动片的形式开发。使用热重分析法测量了各种成分的热稳定性,并开发了刹车片。根据工业标准测试了开发的制动衬块的物理,机械和热性能。根据SAE J661,使用Chase测试分析了摩擦学性质。使用扫描电子显微镜进行表面磨损分析。

发现

实验结果表明,填充有预混合的双金属硫化物的制动衬块具有良好的热稳定性,物理,化学和机械性能,具有稳定的摩擦力,并且由于润滑效果更好,可防止摩擦起伏,因此磨损率更低。

创意/价值

本文解释了在制动衬块配方中预混合的双金属硫化物替代三硫化锑对防止摩擦起伏增强摩擦学性能的影响。
