EXPERIMENTAL INVESTIGATIONS OF EFFECT OF HEATED ABRASIVES ON ABRASIVE JET COATING REMOVAL RATE ON THE SOFT BASE MATERIALS
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 3
Abstract
Coating removal is an important process during the recondition and recoating process of ship base section, bigger structures, marine components, windmill wings and other engineering components. It is essential to remove and clean the existing painting and coating before repainting. The improper and uneven coating removal leads to higher stress concentration. The surface quality of a coated removed surface is critical as it leads to various failures [2]. This work deals with the development of abrasive jet nozzle and fabrication of heated abrasives for coating removal [5]. An experimental setup will be designed and developed in order to investigate the effect of a stand of distance,the temperature of abrasive and an exit diameter of the abrasive jet nozzle on coating removal rate.[6] Abrasives such as SiC, Garnet have commonly used abrasives for achieving a smooth finish with higher material removal rate. Coating removal will be taken place as the abrasives impinge on the surface of the work -piece [7]. When the heated abrasives strike the surface, due to the high temperature of the abrasives it was found that the coating is separated from the surface and there is an increase in material removal rate (MRR).
