    2. Solid-state treatment: case-hardening or solid carburizing

    This process is mentioned here only as a reminder. It is practically no longer used industrially. However, carburizing powders are still marketed for one-off jobs and operations that exceed the capacity of atmospheric furnaces.

    The principle is to embed the parts to be treated in a solid charcoal-based cement, the whole being held in a closed box heated to case-hardening temperature (900 to 950°C).

    • Cement consists of amorphous carbon, usually charcoal with the addition of an activator, barium carbonate BaCO 3 . It comes either in the form of granules reconstituted from a mixture of charcoal (60 to 75%) and barium carbonate (25 to 40%) powder, or as finely crushed pieces of charcoal coated with barium carbonate in the presence of...
