METHOD FOR SPUTTERING ULTRA-PLASTIC ZN-AL ALLOY

PURPOSE:To simplify heat treatment and surface treatment for enhancing strength and to reduce production cost, by carrying out the sputtering of an eutectoid alloy based on Zn and Al which is a fine crystal grain ultra-plastic alloy in such a state that said eutectoid alloy is heated to an eutectoid...

Zusammenfassung:	PURPOSE:To simplify heat treatment and surface treatment for enhancing strength and to reduce production cost, by carrying out the sputtering of an eutectoid alloy based on Zn and Al which is a fine crystal grain ultra-plastic alloy in such a state that said eutectoid alloy is heated to an eutectoid temp. or more. CONSTITUTION:A fine crystal grain ultra-plastic alloy, for example, a Zn-Al eutectoid alloy having a standard composition consisting of 22wt% Al and the remainder Zn is sputtered. At this time, while the Zn-Al alloy is held an eutectoid temp. or more, for example, at about 500 deg.C, for example, Ni is sputtered. By this method, tensile strength is enhanced about 60-70%.
