Spraying Process

This paper aims to study the correlation between some parameters of the metalspraying by APS process and the level of chromium oxide (Cr2O3) adhesion to the base material. Among the properties of the layers deposited by APS are those of wear resistance. In the context of evaluating the coatings properties and understanding aspects related to the coat structure phenomena, the purpose of the experiment presented here is to characterize the adherence of thermal sprayed coating Cr2O3. Because, the main problem of metalspraying layers is adhesion to the base material, there were subjected to tensile testing 2 samples made by 1C45 steel, which were previously bonded with an epoxy glue. The adhesion of the deposited layer on the basic material is important for ensuring the quality of products. The results show that the quality of surfaces and the existence of accidental defects at the interface lead to a decrease of adherence.

Proportionality Limit

The paper presents the results of testing the bending stress of Serbian spruce wood from natural stands. In testing the samples, in addition to the modulus of rupture, the bending stress at the proportionality limit, the ratio between the stress at the proportionality limit and the modulus of rupture as well as the modulus of elasticity of wood were determined. The study included nine trees from natural stands, and a total of 261 samples were tested. Regression analysis determined the dependences of these mechanical properties on the annual ring width, the proportion of late wood and wood density, as well as the dependence of the modulus of elasticity on the modulus of rupture.

Spraying Process

In times of peace the salvaging of worn parts is not usually a major problem confronting the mechanical engineer. Every consideration is given to new materials and to novel designs, but except for those engaged on works maintenance, the returning of old parts to service has not in the past received enough attention from professional engineers. In war time, however, the repair of damaged material becomes a national duty. Although metal spraying by the wire process has become more widely known during the past two decades, the number of engineers who would feel competent to judge its suitability for any repair is comparatively small. The object of the present paper is to describe certain matters of interest to engineers in connexion with this form of salvage. It is not proposed to give details of metal spraying tools or pistols, as descriptions of these may be consulted in the technical press (Rollason, Turner, and Budgen 1939).† For the same reason an account of the many parts normally repaired by this method (Ballard 1942; Ballard, Fairbairn, and Pilkington 1942) is omitted. Metal spraying is being used commercially to a very large and increasing extent for reclamation work. To assist engineers faced with the problem of repairing a worn part, the author has arranged the paper in the form of answers to the following questions: ( a) Is metal spraying a suitable method of reclamation? ( b) If so, how must the work be prepared for spraying? ( c) What method of spraying and which metal should be used? ( d) What finish is necessary?
