Table 7A-2 Spray Conditions

The PlasmaGun spray conditions indicated above are provided as a general guide and represent optimum operating conditions for general spray coating applications. Arc current, plasma gas flow rates, powder gas flow rates and powder feed rates can be altered to suit coating requirements and work piece configuration.

Argon is recommended as the most universally useful plasma working gas.  Other gases, such as nitrogen and combinations of gases such as argon / hydrogen or nitrogen / hydrogen can also be used where increased temperature of the work piece does not adversely affect bond strength, or where increased oxide formation in the coating is not objectionable.

PlasmaGun Spray Powders are selected and processed to provide optimum results when used with the PlasmaGun System.  Chemical purity and particle size distribution are closely controlled to insure that coatings and coating properties are routinely repeatable.

To maintain the high powder quality during storage, containers should be tightly sealed and protected against moisture pick-up.  Powder containers should be tumbled prior to removing powder to guard against powder particle separation due to settling.

The properties and potential uses of these materials and the hazards, if any from handling and using them are not fully known. No express or implied warranties are made.
