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.
