In this work, electroless nickel has been deposited onto steel substrates by a selfcatalytic process, which involves temperature and time to create a Ni–P layer with a uniform thickness. The major drawback of electroless nickel is the interdiffusion post heat treatment (PHT) that is necessary to create a metallurgical bond between the steel substrate and the Ni–P deposit.
