Abstract

An alloy composite material comprising an aluminum alloy layer and a thermal spray alloy layer of 20 to 40% Mn and 47 to 76% Fe by weight in overlaying contact with the aluminum alloy layer. An alloy composite material comprising an aluminum alloy layer or base layer and a thermal spray alloy layer of 20 to 40% Mn and 47 to 76% Fe by weight in overlaying contact with the aluminum alloy layer or base layer. The aluminum alloy layer or base layer and the thermal spray alloy layer have a mechanical compatibility to each other of 20-60 MPa as determined using tests specified by ASTM-C633 test. A process of thermal spraying comprising providing a base layer and a feed stock alloy of 20 to 40% Mn and 47 to 76% Fe and thermally spraying the feed stock alloy onto the base layer to form an alloy composite material.
