Properties Evaluation of Electroless Ni‐Coated Low‐Carbon Steels

Abstract

Electroless deposition or chemical coating is a well-established industrial technique that is gaining popularity. The purpose of the current investigation was to determine how long a heat treatment process had on the mechanical and corrosion performances of a Ni-P coating on low-carbon steel. The coating is performed on the low-carbon steel using Ni-P salt bath. The coated samples were heat treated at 400°C under atmospheric condition using muffle furnace. The heat treatment offers greater corrosion resistance and mechanical qualities. The coated samples were analysed using scanning electron microscope for morphological studies and X-ray diffraction analysis for phase change during heat treatment. According to the experimental findings, a heat treatment prior to coating with Ni-P layer increases hardness and corrosion resistance while lowering friction.

Effects of hydrogen permeation on the mechanical characteristics of electroless nickel-plated free-cutting steel for application to the hydrogen valves of hydrogen fuel cell electric vehicles

“…Therefore, it is thought that the amorphous nickel—phosphorus alloy was predominantly deposited on the substrate surface, resulting in a strong peak at the 2-theta degree corresponding to free-cutting steel. In particular, the relative decrease in and the broadening of the peak at 44.62° are thought to be results of the nanocrystalline nickel structure and the amorphous nickel—phosphorus alloy structure being deposited together during electroless nickel plating [ 44 , 45 ].…”
