Application of Liquidmetal-Armacor Coatings is similar to that of traditional hardfacing materials. Recommended spray parameters for Liquidmetal-Armacor Coatings products have been developed to facilitate the amorphous transformation and optimize the wear characteristics of the coatings. These parameters have been ultilized with a variety of thermal spray equipment in successful field applications. Coating quality has been confirmed by supporting laboratory data.
Surface Preparation
 |
Surface preparation is very important when applying Liquidmetal coatings products. A well-defined surface profile is necessary to provide an anchor pattern for the coating. When properly prepared, the bond strength of Liquidmetal-Armacor Coatings is excellent (6,000 - 8,000 psi). Follow these steps to achieve the desired surface:
- Grit blast, rather than sand blast, due to the more aggressive profile achieved. Recommended products include Aluminum Oxide compounds, Black Beauty or Starblast.
- Grit blast to a white metal finish with clean coarse grit and dry, oil-free air.
- Prepare a surface profile of 3-5 mils
- Surface should be free of grit blast residue before the Liquidmetal coating is applied.
