\n\t\t\t\t\t\t\t\t\tOs p\u00f3s met\u00e1licos pulverizados a frio podem ser usados n\u00e3o apenas como revestimento, mas tamb\u00e9m como um componente manufaturado aditivo. Em compara\u00e7\u00e3o com os m\u00e9todos de tecnologia aditiva de laser ou feixe de el\u00e9trons, a tecnologia aditiva de spray a frio tem tempo de produ\u00e7\u00e3o mais curto, alta flexibilidade de tamanho e n\u00e3o \u00e9 afetada pela alta refletividade do cobre, alum\u00ednio e outros metais no laser. Nosso p\u00f3 met\u00e1lico atomizado a g\u00e1s, especialmente projetado para pulveriza\u00e7\u00e3o a frio, est\u00e1 dispon\u00edvel em uma ampla variedade de ligas, incluindo cobre puro, CuAg, CuAgZr, CuCrZr, CuZn, CuCrNb e alum\u00ednio puro, A357, Al2204, Al6061, Al7050, Al5052, A380, Al7075, Al5056, AlSi10Mg.\n\nDurante a pulveriza\u00e7\u00e3o a frio, os p\u00f3s s\u00f3lidos PSD 0-50um s\u00e3o acelerados em um\u00a0supers\u00f4nico<\/a>\u00a0jato de g\u00e1s a velocidades de at\u00e9 cerca de 1200\u00a0m\/s<\/a>. Durante o impacto com o substrato, as part\u00edculas sofrem\u00a0deforma\u00e7\u00e3o pl\u00e1stica<\/a>\u00a0e aderem \u00e0 superf\u00edcie.\u00a0pulveriza\u00e7\u00e3o t\u00e9rmica<\/a>\u00a0t\u00e9cnicas, por exemplo,\u00a0pulveriza\u00e7\u00e3o de plasma<\/a>, pulveriza\u00e7\u00e3o por arco,\u00a0pulveriza\u00e7\u00e3o por chama<\/a>ou combust\u00edvel de oxig\u00eanio de alta velocidade (HVOF<\/a>), os p\u00f3s n\u00e3o s\u00e3o derretidos durante o processo de pulveriza\u00e7\u00e3o.\n\nH\u00e1 v\u00e1rios fatores que podem afetar a qualidade dos revestimentos pulverizados a frio e a efici\u00eancia da deposi\u00e7\u00e3o. Os principais fatores de influ\u00eancia s\u00e3o:\n
    \n \t
  • Tipo de g\u00e1s, por exemplo, ar, nitrog\u00eanio, h\u00e9lio<\/li>\n \t
  • Press\u00e3o do g\u00e1s<\/li>\n \t
  • Temperatura do g\u00e1s<\/li>\n \t
  • Tamanho da part\u00edcula<\/li>\n \t
  • Propriedades do material de mat\u00e9ria-prima, por exemplo, densidade, resist\u00eancia, temperatura de fus\u00e3o<\/li>\n \t
  • Tipo de bocal<\/li>\n \t
  • Substrato<\/li>\n \t
  • Cin\u00e9tica de deposi\u00e7\u00e3o (velocidade transversal da pistola, velocidade de varredura, n\u00famero de passagens...)<\/li>\n \t
  • Dist\u00e2ncia de afastamento, a dist\u00e2ncia entre o bico de pulveriza\u00e7\u00e3o a frio e o substrato.<\/li>\n<\/ul>\n \n\nNossos p\u00f3s atomizados em \u00e1gua com p\u00f3s muito finos t\u00eam in\u00fameras vantagens para a manufatura aditiva por spray a frio e tamb\u00e9m s\u00e3o uma maneira extremamente econ\u00f4mica para processos de deposi\u00e7\u00e3o de metal por spray a frio. Isso se deve aos custos de fabrica\u00e7\u00e3o muito mais baixos da atomiza\u00e7\u00e3o em \u00e1gua em compara\u00e7\u00e3o com a VIGA, especialmente para impress\u00e3o 3D por spray a frio com base em ferro, como 316L, Invar 36, 300M, M2, 304L.\n\n \nAlguns p\u00f3s de liga de tit\u00e2nio mais caros e p\u00f3s de liga de n\u00edquel tamb\u00e9m s\u00e3o usados na pulveriza\u00e7\u00e3o a frio, comoCP Ti, Ti6Al4V e Inconel 718, Inconel 625, NiCr8020, n\u00edquel puro. A pulveriza\u00e7\u00e3o a frio de t\u00e2ntalo e ni\u00f3bio, ainda mais cara, est\u00e1 sendo estudada devido \u00e0 sua temperatura mais baixa em compara\u00e7\u00e3o com a pulveriza\u00e7\u00e3o t\u00e9rmica.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
