Title:
ZINC-BASED ALLOY SHOTS
Document Type and Number:
WIPO Patent Application WO/2011/052287
Kind Code:
A1
Abstract:
Provided are zinc-based alloy shots which, without risk of dust explosion, are capable of high performance deburring and abrasion cleaning through shot blasting and application of compressive residual stress through shot peening, with low quantities of shots consumed by shot projection. The zinc-based alloy shots include a three-component zinc-based alloy shot wherein 0.5 - 6.5 mass % Al, 0.5 - 4.5 mass % Cu are contained as additional elements, the mass composition ratio of Al to Cu (Al/Cu) is 1.0 - 13.0, the total amount (Al + Cu) is 1.5 - 10.5 mass %, and the Vickers hardness is 90 - 190 HV; and a four-component zinc-based alloy shot wherein 0.5 - 6.5 mass % Al, 0.5 - 4.5 mass % Cu, 0.01 - 0.2 mass % Mg are contained as additional elements, the mass composition ratio of Al to Cu (Al/Cu) is 1.0 - 13.0, the total additional amount (Al + Cu) is 1.5 - 8.0 mass %, and the Vickers hardness is 90 - 190 HV.
