Abstract
Samples of 4340 steel have been borided in a cold rf plasma initiated in a gas mixture of 2.7% diborane in argon. The plasma borided surfaces have been investigated by scanning electron spectroscopy, X-ray diffractometry. Auger electron spectroscopy, and microhardness measurements. It was found that as a result of the dissociation of the diborane in the plasma boron is deposited on the surface of the steel substrate, and two crystalline phases are formed: tetragonal Fe 2B and orthorhombic FeB. Due to the formation of the boride phases, the surface microhardness increased from the original value of 2650 MPa (270 kgf/mm 2) to a maximum value of 7740 MPa (790 kgf/mm 2).
