Abstract: This paper mainly deals with various Chromium coating defects that occur while electro plating of different mechanical components and methodology adopted to prevent it. It also covers suggestions to minimize this problem. This paper contains new suggestions to minimize the problems by using recent technological developments. Since the chemicals used for chromium coating are posing threat to environment it is need of the hour to minimise the use such chemical consumption. The reduction in defective components will increase productivity as well as protect the environment to some extent It also describes the various alternate coating methods for chromium coating through which we can achieve the required surface properties. India being a Developing country .for various coating application chromium is used. Since the process is slow and involves lengthy cycle time unless the defects are minimized the products cannot be delivered in time which will create loss to the Industries. Being the cheaper & simple technological process it is being used for coating applications. Disposal of effluents generated by this chromium coating process has to be taken care of by the Industries which are using the process. By using the chromium along with other materials, defects can be minimized as well as better surface properties can be obtained. This paper describes the techniques and gives details of chromium coating applications in various Industries.
