dc.description.abstractIn addition to being used by industry as a means of surface cleaning and of imparting a matt finish for subsequent operations, vapour blasting has also been used as a means to improve the fatigue life of parts made of aluminium alloys. The present work investigates the effect of vapour blasting on the fatigue life of age-hardened aluminium alloys, using 6063 aluminium alloy as a model material. It is shown that vapour blasting not only produces a hardened surface layer but also roughens the surface of the material. This, in turn, produces an intricate effect on the fatigue life of the material. At low blasting pressures, both the surface hardness and the depth of hardening increase significantly while the surface roughness degrades only moderately with blasting pressure. This gives rise to an increase in fatigue life. On further increasing the blasting pressure, however, while the rate of surface hardening gradually saturates, there is an abrupt increase in the surface roughness due to severe cuts and deep indentations produced by the high velocity abrasive. This causes the fatigue life of the material to decrease at high blasting pressures. The present work shows that there exists an optimum blasting pressure beyond which the fatigue life of age-hardened aluminium alloys degrades with a further increase in blasting pressure. © 1995.
