Application Of Design Of Experiments In Metal Coating Process Improvement, Mayur Mohite

Culminating Projects in Mechanical and Manufacturing Engineering

RIE Coatings was experiencing an average of 8% fallout in the recess area coating quality of parts. Coating in the recess area used to peel off, crack and was resulting in customer complaints. The objective of this project was to reduce the coating defect in the recess area of different parts and thereby set up an experimentation process to bring down the defect rate from 8% to 4% of the batch. Different factors responsible for quality of the recess coating quality were identified. Factors such as load and spin time were tested at different levels. Two -way analysis of variance …
