Conclusions
-
1.
A process has been developed for phosphatizing carbonyl iron powder.
-
2.
It is shown that cores made from phosphatized powder meet all the requirements laid down by technical specifications and exhibit a much higher thermal stability than cores made with water glass.
-
3.
The investigation has demonstrated the need for early adoption by industry of the new process for phosphatizing carbonyl iron powder.
