Corrosion Activity in 1965 Part I
The prospect of a sharp increase in the attack on some ofthefundamental problems of corrosion warrants a general review of current activities in anticorrosion protection research. To this end, we o$er, f o r the nonspecialist reader, the j r s t part of a general compilation of the published literature from 1965, indicating the scope oftheproblems and the attempts being made to solve them
corrosion protection to be increasingly inadequate, especially with respect to predicting performance from accelerated test data. These conferences have also provided incentives for closer liaison between the two major groups interested in corrosion problems-i.e., the corrosion engineers and the solid-state scientists.
designing materials for corrosive service, the corrosion engineers are faced with an ever increasing array of materials, metallic and nonmetallic, for which there is no great backlog of performance data. As a result, they are occasionally required to invent new, and sometimes questionable, techniques for rapid evaluation of materials. I n view of the great capital outlay involved in most designs, which makes a cautious approach with a minimum of innovation desirable, it is truly remarkable that the corrosion engineers have succeeded as well as they have. The solid-state scientists, primarily physicists and electrochemists, are generally not immediately concerned with corrosion problems. At the same time, the increase in their activities in recent yean has provided much basic information, particularly in the areas of instrumentation and data correlation, which is of great sing importance to the corrosion engineers.
