Surface Treatment & Painting

This course provides a comprehensive understanding of surface treatment and painting processes used to protect and enhance engineering components and products. It covers surface preparation methods required before coating and painting to achieve proper adhesion and long-term durability. Participants learn about cleaning, degreasing, abrasive blasting, phosphating, conversion coatings, and other surface treatment techniques. The course explains different types of paints, primers, coatings, and their selection for various industrial applications. It covers application methods such as spray painting, dipping, brushing, powder coating, and electrostatic painting. Participants understand coating thickness, curing methods, drying conditions, and parameters affecting coating performance. The course also addresses corrosion mechanisms and methods for improving corrosion resistance through suitable surface treatments. Quality control techniques such as adhesion testing, coating thickness measurement, visual inspection, and defect analysis are discussed. Common painting defects, their causes, and corrective actions are explained with practical industrial considerations. The course helps participants develop knowledge required to select, control, and optimize surface treatment and painting processes for improved product quality, appearance, and service life.
