In this research, specimens of aluminum alloy 6061 were
received, and chemical composition was investigated. After
that solution heat treatment was applied on it at 530°C, a
section of these specimens was quenched in water and anther
quenched in
oil, and two sections were aged at 160°C for
times (1,3,5 h), and thus obtained six samples differ in
condition of heat treatment in addition to as received
specimen.
In This research a surface hardening process by Ni coating and
subsequent diffusion heat treatments was studied at Al7075 alloy.
Nickel coatings with different thickness were obtained.
