Abrasives, such as oxides of alumina (Al), silica (Si), zirconia (Zr), chromium (Cr) etc., are added to raise the friction level and also to remove the glaze on the disc so that surface will be rejuvenated continuously during braking and will contribute to maintain the desired friction level. However, these inorganic particles have less adhesion with the resin/binder and hence are easily dug out during wearing process contributing to higher wear. If efforts are made to enhance the filler-matrix adhesion, not only the wear of friction material (FM) should reduce, the particles may stay for a longer time on the tribo-surface of the pads to contribute fully towards controlling the coefficient of friction (μ). In the present study, alumina particles were selected for siloxane treatment to improve the filler-matrix adhesion. Two types of eco-friendly (free from asbestos and Cu) brake-pads were developed using alumina as a theme ingredient (treated and untreated) keeping all the parent formulation identical. An additional type of brake-pads without alumina particles was also developed to observe the effect of abrasive particles on the tribo-performance. The performance properties (physical, mechanical, and tribological) of brake-pads were compared when evaluated in identical conditions. The tribo-testing was done on full-scale brake inertia dynamometer following the procedure in Japanese automobile standard (JASO C 406). It was observed that siloxane treatment affected both friction and wear of brake-pads in a beneficial way. Wear resistance got increased 35% for siloxane treated pads. Worn surfaces were analysed using scanning electron microscopy (SEM) and energy dispersive X-ray (EDAX) technique.

加入磨料，例如氧化铝（Al），二氧化硅（Si），氧化锆（Zr），铬（Cr）等氧化物，以提高摩擦力，并去除圆盘上的釉料，使表面恢复活力在制动过程中连续不断，将有助于保持所需的摩擦水平。然而，这些无机颗粒与树脂/粘合剂的粘附性较小，因此在磨损过程中容易被挖出，从而导致较高的磨损。如果努力提高填充物与基质的粘合力，不仅应减少摩擦材料（FM）的磨损，而且颗粒可能会在摩擦垫的摩擦表面上停留更长的时间，从而完全有助于控制摩擦系数（μ）。在本研究中，选择氧化铝颗粒进行硅氧烷处理以改善填料与基质的粘合力。使用氧化铝作为主题成分（已处理和未处理）开发了两种类型的环保型（无石棉和铜）刹车片，使所有母料配方保持一致。还开发了另一种不含氧化铝颗粒的刹车片，以观察磨料颗粒对摩擦性能的影响。在相同条件下进行评估时，比较了制动片的性能（物理，机械和摩擦学）。摩擦测试是按照日本汽车标准（JASO C 406）中的程序在满量程制动惯性测力计上进行的。观察到硅氧烷处理以有益的方式影响了制动片的摩擦和磨损。硅氧烷处理过的垫的耐磨性提高了35％。使用扫描电子显微镜（SEM）和能量色散X射线（EDAX）技术分析磨损的表面。
