Compounds of the element boron
will vaporize and react with steel and other alloys to convert a diffused
layer at the surface of parts to an extremely hard compound, which has
superior wear resistance. Parts are borided by heating them in a furnace
in an atmosphere containing these boron compounds. The parts, heated to
temperatures in the 1800F range for several hours, can be used directly
after the boriding treatment in applications requiring extreme wear
resistance. Examples would include spray
