The new high-strength stainless steels alloyed by copper and nitrogen and possessing high resistance to corrosion by active micro-organisms in carbon-oxidizing, heterotrophic and sulfate-regenerating bacteria mediums are developed. The introducing of small addition of nitrogen (about 0.22 %) to the corrosion resistant steel С0.5Cr15Ni5Cu2NMoNbTi results in a decrease of adhesive micro-organisms quantity on a sample surface by 8 times, while increasing of nickel content to 9 % results in their decrease only by 2 times. It is supposed that the effect of nitrogen can be related to formation of biocide substances. High copper (Cu = 2.5-5 %) nitrogen-containing cast steels are in austenitic (non-magnetic) condition. Due to a dendritic segregation, the structure of steel corresponds to a natural composite structure, and it is preserved on heating to high temperatures. After cold deformation with up to 85 % reduction, the steels preserve austenitic structure, and its hardness attains a level close to the hardness level of the martensitic structure. The developed corrosion-resistant antimicrobial steels with the increased hardness can be used as a material for the surgical instrument.

Adhesive Bonded Joints

Durability of adhesive bonded joints in moisture and salt spray environments is essential to USAF aircraft. Structural bonding technology for aerospace applications has depended for many years on the preparation of aluminum surfaces by a sulfuric acid/sodium dichromate (FPL etch) treatment. Recently, specific thin film anodizing techniques, phosphoric acid, and chromic acid anodizing have been developed which not only provide good initial bond strengths but vastly improved environmental durability. These thin anodic films are in contrast to the commonly used thick anodic films such as the sulfuric acid or "hard" sulfuric acid anodic films which are highly corrosion resistant in themselves, but which do not provide good initial bond strengths, particularly in low temperature peel.The objective of this study was to determine the characteristics of anodic films on aluminum alloys that make them corrosion resistant. The chemical composition, physical morphology and structure, and mechanical properties of the thin oxide films were to be defined and correlated with the environmental stability of these surfaces in humidity and salt spray. It is anticipated that anodic film characteristics and corrosion resistance will vary with the anodizing processing conditions.
