Abstract

Little attention was paid to zinc matrix composites in the past, due to the high density of zinc, but its very low melting temperature allows a very easy manufacturing process and thus its industrial use as a structural material may be expected in the future.

In the case of zinc matrix reinforced by stainless steel filaments, a comparative study is performed in order to establish a relationship between manufacturing process and the mechanical features of this material.

In this paper, samples are manufactured by hot press under vacuum of SS/Zn monolayers. The matrix included in such monolayers was apported via electrolytic deposition or by liquid metal infiltration. Just before incorporation in the zinc matrix composite, the stainless steel filament could optionally be surfacially activated by pickling in a bath having controlled acidity.

The mechanical performance of SS/Zn composites is strongly influenced by the duration of the sintering period and activation of the steel filament. The fracture energy depends on the failure mode (transfibrilar or flexure breakdown) and surface pre-treatment of filaments. For electrodeposited matrix, short sintering periods yield better toughness, but for infiltrated matrix three hours consolidation are recommended.
