This book covers the fundamental relationships between solid surface chemical reactivity and the stressed state of surface layers; developed mainly by the author. Acceleration of chemical reactions by mechanical action (mechanochemical effect) and near-surface plasticity increase caused by chemical reactions (chemomechanical effect) acting simultaneously; open new possibilities for the control of a wide range of processes from corrosion to new materials engineering.This monograph is a unique work on this subject and will be essential reading for undergraduate and postgraduate students engaged in studying surface phenomena in materials science; chemistry and chemical engineering; as well as for scientists and engineers in the industries where these phenomena are important.
