One of the most effective methods of increasing the wear resistance,
hardness, surface strength and high-temperature oxidation resistance of
metals and alloys is the diffusion satu- ration of the surfaces by
metals and nonmetals. For communicating and discussing the results of
the numerous researches carried out in this field in the Department of
PJ: tysicotechnical Problems of Materials Science, Academy of Sciences
of the UkrSSR, a permanent Scientific Seminar was set up in 1961, which
enjoys an ever-increasing popularity among specialists in this field.
The present collection contains papers read at the Third Session of this
Seminar, held on September 25-28, 1963. The compilers of the collection
and the authors of the papers hope that its publication in the U. S. A.
will enable American specialists to become acquainted with the main
lines along which corresponding work is being conducted in the USSR.
This should contribute to an ex- change of scientific experience in this
interesting field which is of such great practical impor- tance. G. V.
Samsonov PREFACE This collection is comprised of papers relating to the
diffusion saturation of metals and to coatings of refractory compounds.
The papers discuss current problems in the theory and practice of the
production of diffusion coatings on metallic materials. A means of
classifying the methods of diffusion saturation is proposed, and a new
method is described for calculating the diffusion parameters in a
heterogeneous medium.
