Selection of crucible material for electrolyte boriding
- 21 Downloads
For boriding of a small set of articles (especially of large articles) in an electrolytic boriding unit, a welded crucible made out of heat-resistance steel can be used without cathodic protection.
To prove that an economic calculation should be carried out. If it is possible to manufacture a case crucible out of an alloy with low anodic solubility, which makes it possible to keep the Y values within permissible limits, then it is feasible to design a unit where the crucible serves as anode.
