“…Sugere-se que esta inversão em relação às outras temperaturas de pré-aquecimento ocorra pela mudança de morfologia da panqueca de "fragmentada" para "disco", elevando a taxa de resfriamento, [28]- [31].…”

“…El gas o la mezcla de ellos atraviesan el arco y se calienta a temperaturas elevadas (8.700 °C a 12.000 °C) que parcialmente lo ioniza produciendo el plasma [32]. A la salida de la boquilla, el gas se asocia nuevamente liberando gran cantidad de calor, para fundir los materiales del recubrimiento, en forma de polvo.…”

“…The detrimental effects of splashing include the formation of voids that are difficult to fill by the subsequent droplets, reduced time for substrate melting and reduced pressure in the splash drops [10]. The presence of oxides or hydroxides at the interface might inhibit the contact between the two materials; if these are thin enough, however, localized substrate melting, jetting and interdiffusion are still possible [22]. Preheating appears to improve the wettability of the substrate by the particles, thereby enhancing the adhesion, even in cases of splashing [15].…”
