The Matrix

A wear resistant TiC-Cr7C3/Fe surface composite was produced by cast technique and in-situ synthesis technique. The microstructure and dry-sliding wear behavior of the surface composite was investigated using scanning electron microscope(SEM), X-ray diffraction(XRD) and MM-200 wear test machine. The results show that the surface composite consists of TiC and Cr7C3as the reinforcing phase, α-Fe and γ-Fe as the matrix. The surface composite has excellent wear-resistance under dry-sliding wear test condition with heavy loads.

Welding Seam

The AZ91D composites reinforced by 10 wt.% AlN particles were welded via plasma welding and the dry sliding wear properties of the composites were investigated. The influence of welding current, welding speed and plasma flow rate were studied in detail. By using of OM, XRD, EDS and SEM, the crystalline phase, the microstructure and the wear properties were investigated. The experiment result shows that the AlN reinforcing particles is in the shape of strip and have a fine size under the condition of the welding speed 400 mm/min, the welding current 180 A and the plasma flow 2.0 L/min, which reaches 20–30 μm. The matrix grain in the composite were obviously refined, which reaches 60–70 μm. Wear test results showed that the wear rate of welding seam compared base metal decreased by 25%.

Particulate Reinforced

In the current investigation an attempt has been made and to produce ceramic Al2O3particulate reinforced 6061Al matrix composites by liquid metallurgy route (stir casting technique) and to study the dry sliding wear properties of the prepared composites. The amount of ceramic Al2O3particulate reinforcement addition was maintained at 9 and 12wt%. During the preparation of each composite the ceramic reinforcements were introduced in a novel way which involves three stage additions of reinforcements during melt stirring. The wear tests were conducted using pin on disc wear testing machine on 6061Al matrix before and after addition of Al2O3reinforcements Wear test results demonstrated the superior wear resistance of the composites over monolithic 6061Al alloy matrix.

Primary Si

The effects of the primary Si phase and applied load on the dry sliding wear behaviors of hypereutectic Al-20Si alloy were investigated. The results show that coarse polygonal and star-like primary Si was refined into fine blocky shape by increasing superheat treatment temperature. The friction coefficient and wear rate significantly decrease after decreasing the size and changing the morphology of primary Si. Moreover, the friction coefficient and wear rate increase with the increase of applied load. Therefore, the wear properties are greatly influenced by the parameters like morphology and size of primary Si as well as applied load.
