Solid erosion of as cast and treated 19.5%(volume fraction) Al 18 B 4O 33 whisker/AC4C Al composites was investigated at room temperature under steady state conditions. The results indicated that the interfacial reaction between the whisker and matrix alloy have an effect on the erosion characteristics of the composites. The erosion resistance of the composites with a strongly bonded whisker matrix interface and the higher whisker strength resulted from suitable reaction treatment can be improved at high impact angles and is the same as the as cast composites at low angle. For the composites after excessive reaction treatment, the weak and brittle interface fractures easily at small strains, and the whiskers with relative low strength and low hardness at the specimen surface can not effectively resist the microcutting or microploughing action, thus the composites exhibit reduced erosion resistance.

The reaction of bis(dibromophenylstannyl)methane with 1, 3-bis(3, 5-dimethyl- pyrazol-1-yl)propane in a 1:1 or 1:2.ratio yields only 1:1 adduct which partly hydrolyzes to the title complex (C2.H38Br6N4O2.n2.
