Abstract

NiCrAl-diatomite coatings, nickel graphite coatings and Ag-Cu alloy coatings prepared by thermal spraying were used to study the reaction mechanism. The compositions of NiCrAl-diatomite, nickel graphite and Ag-Cu alloy powders and coatings were investigated by X-ray diffraction. The powders were analyzed by thermogravimetric differential thermal analysis and scanning electron microscopy. The powders and coatings were compared and found to have the same phase by X-ray diffraction. Thermogravimetric differential thermal analysis of the powders showed that NiCrAl-diatomite was almost stable below 800 °C. Ag-Cu alloy coating and nickel graphite coating cannot be used at temperatures above 700 °C and 400 °C, respectively.
