Abstract
A heating apparatus and method of making such apparatus has a deposited heating element of oxidized metal powder. The metal powder is oxidized more than forty percent and preferably between sixty and ninety-five percent. The oxidation is the deposited metal powder is increased by either modifying the powder or the modifying the deposition process. The powder is modified by preoxidation, reducing the size of particles, removing oxidation inhibitors, adding oxidation catalysts and enhancers and increasing the surface area of the particles. The process of deposition is modified by using more oxygen and using a high velocity oxy-fuel plasma deposition process.
