The effect of nickel base brazing powder additions on the corrosion behaviour of sintered austenitic stainless steel 1N H2SO4 has been investigated. It has been found that the corrosion resistance of the sintered mixture increased substantially and proportionally to the brazing powder content in the range 1 wt% to 5 wt%. The improvement in the corrosion resistance originates from the reduction in the open interconnected porosity due to the formation of a transient liquid phase. A corrosion resistance similar to wrought austenitic stainless steel was observed in the presence of 5 wt% fine grained additive. A substantial change in the pore morphology, grain size and grain structure has been observed with increment in the quantity of the fine particle size additive. The presence of coarse particle size additive has only local effect and does not affect substantially the environmental behavior of the sintered samples.
