摘要: NiAl have been produced by a self-propagating high-temperature synthesis (SHS). The power source that ignite the SHS reaction is concentrated solar energy. coatings are obtained in few seconds and processes economic environment friendly. Three different mass tested: 0.3; 0.6 y 1.7 g. Coating porosity adherence to substrate depends on mass. Pores large samples with g while other specimens small pores. better when amount of reactive powder larger.
