PROCESS 08 - SURFACE TREATMENT Abrasive Blasting & Chemical Passivation
Precision blasting creates uniform micro-surface texture to enhance paint adhesion and sealing performance. Chemical passivation forms a conversion film on critical structural components, drastically boosting corrosion resistance and extending product service life under high humidity, salt spray and alternating temperature working conditions.
