Currently, the most promising technology of coating formation is microarc oxidation (MAO) with unique properties of the surface layer, which combine high wear resistance, corrosion resistance, and heat and erosion resistance. Microarc oxidation can be used for parts and components manufacturing in various segments of industries. However, the technology improvement by improving the tribological characteristics of MAO-coatings can not only enhance economic effect, but also expand its application.

The stable industrial trends towards improvement of product accuracy and quality call for necessity to widen the nomenclature of details surfaces and materials, which need finishing. The method of magnetic abrasive finishing (MAF) helps to meet these challenges. This paper presents the results of study of technological potential of MAF equipment with rotating working area, filled with magnetic-abrasive powder. Such equipment allows to polish the cylindrical, conical and helical surfaces of core details made of magnetic and non-magnetic materials. Geometrical accuracy and roughness of the above mentioned surfaces after MAF and also the conditions of their performance theoretically and experimentally studied. It is established that MAF changes the fine structure of detail surface layer made of hardened high-speed steels, titanium and aluminum alloys and improves their surface performance.

Aluminum and aluminum alloys can be coated with porcelain enamel slip which is fired at 1000°F for approximately 10 minutes. This produces a material with a surface layer (about 0.1 mm thick) which has the properties of porcelain and the basic mechanical properties of a light ductile metal. A problem termed spalling may arise after weathering or exposure to a corrosive salt solution, if the base metal is not chosen carefully or pretreatment of the metal is not correct. A typical failure of this type on a test panel is illustrated in Fig. 1. The spalling failure initiates at pin holes, scratches and edges, then spreads laterally by attack at the interface between the enamel and base metal. An electron fractograph at the edge of a circular spalled area on a test panel of an improperly pretreated 6061 alloy is shown in Fig. 2. The corroded metal is on the bottom and the porcelain on the top. The narrow band through the center is the fracture edge of the porcelain enamel adjacent to the interface.
