Abstract
Procedeul si instalatia de tratamente termochimice în strat fluidizat, conform inventiei, face parte din domeniul tratamentelor termice pentru piese si scule din indutria constructoare de masini si realizeaza operatiile de nitroferoxare si feroxare pentru piese si scule în vederea cresterii durabilitatii acestora. în procedeul conform inventiei se foloseste ca mediu de încalzire o suspensie de particule de nisip sau corindon inerte din punct de vedere chimic cu granulatia de 0,16...0,32 mm, relizata prin insuflare cu aer si amoniac, aer, apa si amoniac sau aer si apa amoniacala la presiuni de 500...1000 mm H2O insuflate la baza retortei în care are loc tratamentul cu astfel de debite încît reportul H2O/H2 sa fie cuprins între 1 si 6, implicit rezultând si concentratia de azot la un punct de roua de 30...50 degree C. Se poate aplica la scule aschietoare, de deformare plastica la rece, de stantare pentru piese solicitate la uzura si oboseala si pentru protectia superficiala a pieselor si sculelor.
