7. SURFACE TREATMENT New Hard Coat for Aluminum. Steel, v. 143, Sept. 22, 1958, p. 80-81. The electrochemical method can deposit coatings more than o.oo6-in. thick, has better wear and heat resistance.
Surface Finish. Metallurgical and Mechanical Aspects. K. G. Lewis. Metal Treatment and Drop Forging, v. 25, Aug. 1958, p. 335-342. The various expressions used in the study of surface finish are described, together with the more important machine and material variables which affect them. Particular attention is paid to chip formation and its influence on surface finish. The effect of metallographic structure is examined at length owing to its bearing on the formation of built-up-edge. Investigations into the mechanism underlying the formation of “smear metal” are described and the various means for its removal compared, the comparison including an examination of the effect of cold-working on surface finish.

Oscar J. Horger and H. R. Neifert. Paper from “Symposium on Large Fatigue Testing Machines and Their Results”. p. 81-95, 1958. American Society for Testing Materials, Philadelphia. Rotating-bending fatigue tests were made on 7-9116 in. diameter normalized-and-tempered 0.50% plain carbon steel shaft forgings having a pressfitted outer disk member. Information is presented on the actual surface rolling of about 27-m. diameter marine propeller shafting.
