Obtaining in esferoidizados households of base alloys of CO Cr, CO Cr Mo alloys and families based on Ni - Cr, for application odontolu00d3gica, obtained by high energy milling

摘要

Summary obtaining in esferoidizados households of base alloys of CO Cr, CO Cr Mo and Ni - Cr, for application odontolu00d3gica, obtained by the grinding of high energy, particularly the invention relates to postgraduate esferoidizados families of alloys which are submitted, The particularity of present themselves as post with regular shapes.Allowing the use for obtaining dental alloys, with advantages in relation to the metal powders obtained traditionally.The invention consists in the following steps: (1) obtaining alloy families based on CO Cr, CO Cr Mo or Ni Cr, high purity obtained by conventional casting, defined in (% by weight); (2) the creation of chips from machining in this league. (3) cleaning chips; (4) sec. Act in the greenhouse in time and predetermined temperature; (5) milling of high energy.Preferably in vacuum or inert atmosphere; (6) the particle size separation of particles; (7) thermal treatment of esferoidizau00e7u00e3o using inert atmosphere or vacuum, temperature and predetermined time; - (8) fragmentation superfici Al and separation selectivity.
