Abstract
The paper discusses the causes and character of the quench cracks that appear when an annular tool is surface-hardened by a plasma jet. A co mbination bulk-and-surface hardening procedure is set out, which impar ts the hear-treated tool high service properties and high manufacturin g strength.
