Abstract:  
Introduction: Specialists in the Coatings industry stress that the effectiveness of a coating is greatly dependent on the component’s pre-treatment process. This is a well-respected fact for some of us in the pre-treatment industry and it is what makes us tirelessly pursue the advancement of pre-treatment techniques. The two widely used types of pre-treatment techniques are mechanical and chemical. Though the manufacturing industry uses both, mechanical pre-treatment such as blast cleaning and grit blasting are preferred due to the environmental concerns associated with the use of chemicals. Pre-treatment requirements are also applicable for downstream processes such as thermal spraying and galvanizing.
