This paper analyzes the control parameters in the fabrication of a tin base composite, using Taguchi method and proposes a suitable combination of input parameters for the optimum self-lubricating characteristics of the composite. The important characteristics of the material required for self-lubricating properties are identified to be high open porosity and reasonably high density. The control parameters chosen are particles size of base material, compaction pressure, sintering temperature, sintering time, and percentage of salicylic acid added as pore forming material. An L8(27) orthogonal array design is used to plan the experimental conditions, with four replications and signal-to-noise ratio (S/N) is analyzed through Pareto Analysis of Variance (ANOVA) and iso-level values to arrive at the optimum combination of input parameters for the material under investigation. It has been concluded that for high overall density, coarse particle size, high compaction pressure, low sintering temperature, high sintering time and low percentage of additive are required, while for high open porosity fine particle size, low compaction pressure, high sintering temperature, low time and high percentage of additive are needed.
