This book presents the most important thermochemical and physical techniques of boriding. The
formation and characterization of different boride layers or boride coatings are compared in
this book. The author analyzes the technological aspects of boriding processes presenting the
advantages and disadvantages of each method. The effect of the boriding techniques on the
microstructure of borided materials are also indicated. The mechanism of formation of active
boron atoms or ions and the phenomena during re-melting of alloying material together with the
substrate are described. Special attention is devoted to powder-pack boriding electrochemical
boriding in borax gas boriding plasma gas or paste boriding and laser or plasma surface
alloying with boron acknowledged as the most important current methods in boriding. The
thermodynamics of gas boriding is also analyzed.
