Airborne wear particle emission has been investigated in a pin-on-disc tribometer equipped with particle analysis equipment. The pins are cut out from commercial powder metallurgy automotive brake pads as with and without copper content. The discs are cut out from a commercial grey cast iron automotive brake disc as cut out and as in addition to a laser cladded with a powder mix of Ni-self fluxing alloy + 60% spheroidized fused tungsten carbide and then fine-ground. Dry sliding wear testing runs under a contact pressure of 0.6 MPa, sliding velocity of 2 m/s and a total sliding distance of 14,400 m. The test results show both wear and particle emission improvement by using laser cladded discs. The laser cladded discs in comparison to the reference grey cast iron discs do not alter pin wear substantially but achieves halved mass loss and quartered specific wear. Comparing in the same way, the friction coefficient increases from 0.5 to 0.6, and the particle number concentration decreases from over 100 to some 70 (1/cm3) and the partition of particles below 7 µm is approximately halved.

Abstract The paper presents the problem of obtaining a permanent diffusional joint between the working surface layer and the base part in a bimetallic casting. The studied bimetallic casting was obtained as a result of using the founding method of layer coating directly in the cast process. The casting prepared using this method consists of two fundamental parts, i.e., the grey cast iron base and the working surface layer which constitutes of X6Cr 13 high-chromium stainless steels plate. Based on the obtained results it was confirmed that the decisive phenomena that are needed to create a permanent joint between the two components of the bimetallic casting are carbon and heat transport from the high-carbon and hot base material which was poured into the mould in the form of liquid metal to the low-carbon and cold material of the working layer which was placed in the mould cavity in the form of a monolithic insert.

Laser cladding is an effective mean to repair the damaged components in remanufacture industry. The iron-based alloy coating was obtainment by laser cladding on grey cast iron (HT250). The microstructure and morphology of laser cladding were observed by using scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). The micro hardness of laser cladding coating was tested. The wear properties of grey cast iron and laser cladding coating at room temperature without lubrication were evaluated by sliding wear tests. The distribution regularity of surface residual stress of substrate and cladding coating was obtained. It was shown that the laser cladding coating on grey cast iron has a homogeneous and dense microstructure. It was observed that the laser cladding coating presents a great hardness and excellent wear resistance. Tensile stress was generated in the surface of laser cladding coating.
