A method for forming protective corrosive resistant coatings on equipment is disclosed. The coating is formed from a NiCrMo alloy composition containing at least two gettering components selected from Al, Si, and Ti in an amount of up to 25 wt. %. The coating in one embodiment is applied using a thermal spray technique, e.g., twin wire arc spray, forming coatings of 5-50 mils thickness having a fine-scale micro-pore structure which is effectively non-permeable in aggressive solutions, and resist selective oxidation in thermal spraying of components for maximized corrosion performance The coating is further characterized as having excellent adhesion strength even when applied with varying parameters as in manual on-site coating applications. |
