Critical Factors For Processing Series 900 Coatings

Coating Thickness

Thermal spray coatings consist of a significant surface growth, typically between 0.005 and 0.008 in for most coatings, with standard process tolerance controlled to ±0.0025. In applications that require close dimensional control, Series 900 coatings are not recommended, unless the specific coating was engineered to be machined after coating.

Coating Removal

Series 900 coatings are engineered "permanent" coatings by design, and can only be removed by means of mechanical blasting, or machining. It is feasible, depending on the specific coating applied and base metal, that the coating will not be removable, and consequently, the part may not be salvageable. Minimally, the tool or part surface may require re-polishing.

Base Metal Surface Requirements

Surface contaminants must be removed prior to processing for effective bonding to substrate. Endura^® will evaluate your current base metal contamination condition to determine the necessary pretreatment requirements prior to processing.

Masking

One of the unique advantages of Series 900 coatings is that the coating can be applied to selected surfaces with the assistance of special masking techniques. In the event masking is required, it must be clearly noted on your print and/or purchase order.
