| Conventional Metal Powder Coatings, designed to obtain anti-corrosive, wear and thermal resistant properties, are studied and their properties are analyzed. The capabilities of the Supersonically Induced Mechanical Alloy Technology are investigated with the purpose to enhance the surface strength and durability, simplify the deposition procedure and increase service time. A new spray deposition process is shown and compared with other different methods of Metal Powder Coating deposition. A new method is developed that is less expensive and operates with similar load mechanisms on powder particles. High strain rate deformation can be easily studied by special powder compaction. In this method, the powder is loaded into a die with skewed punches and deformed under high strain rates. The bonding conditions of powder particles are shown to be similar to those obtained in SIMAT process. The composite microstructure, mechanical properties and special characteristics of the coatings delivered using Supersonically Induced Mechanical Alloy Technology are investigated and described. The methodology used to analyze the mechanical properties of coatings is explained. Experimental results using the ultrasonic scanning systems are presented. |
