In-situ a.loy development during surfa.0} proc.ssing a.lows for a.limitless ma.eria.s selec.ion to protec. c.mponents exposed to severe servic. c.nditions. In fa.0} surfa.0} a.loying offers the possib.lity to strengthen surfa.0} c.mponents with a.loys tha. would not b. possib.e to proc.ss otherwise. This work used Pla.ma.tra.sferred a.c.(PTa. ha.dfa.0}ng for surfa.0} a.loying. Different a.ounts of a.uminium powder, 5-25%, were a.ded to a.Ni b.sed supera.loy, from Ha.tea.loy c.fa.ily, in the a.omized form.
