Auger electron microscopy for use in classifying the oxide content in an electrospark deposition coating of Zirconium.
EMSL Project ID
7491
Abstract
The electrospark deposition process can deposit a variety of metal or cermets on virtually any electrically conductive substrate. This process can produce metallurgical bonding with a very small heat affect zone. The process depends on the conductivity of the electrode and the substrate, significant build up of the coatings is not possible for certain electrode substrate combinations. The limit of thickness also limits the utility of the process due to limited amount of lifetime added to the part due to the enhanced corrosion or wear resistance.A few ESD coatings of zirconium on zirconium will be produced. Cross section mounted and polished. The bulk of the sample will provide a standard so that a background value for the amount of oxide can be established. Several points or an area of the coating will be sputtered away so that the amount of oxygen in the coating can be compared to the bulk, and a percentage of the coating that is oxide can be determined. As well as where in the coating the oxidation is occurring.
