Mf. Stroosnijder et al., THE INTERACTION OF SURFACE ENGINEERING AND HIGH-TEMPERATURE CORROSIONPROTECTION, Materials at high temperatures, 12(1), 1994, pp. 53-66
The interaction between surface engineering and corrosion resistance o
f high temperature materials is reviewed. A brief description is given
of high temperature corrosion, while criteria for surface engineering
are outlined. The most important classes of surface treatments utiliz
ed technologically to provide high temperature corrosion protection, n
amley surface alloying, diffusion coatings and also metallic and ceram
ic overlay coatings, are discussed. The various ways in which surface
engineering can interact with high temperature corrosion resistance ar
e considered. Thus, the main purpose of the surface layer can be solel
y to afford protection, but in other cases, such as with thermal barri
er coatings, the surface layers have another primary task, but additio
nally provide corrosion resistance. Finally, the important role of sur
face modification techniques, in particular ion implantation, as a res
earch tool for corrosion science is highlighted.
