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%.
