Predicted Fracture Behavior of Shaft Steels with Improved Corrosion Resistance

One of the crucial steps in the shaft design process is the optimal selection of the material. Two types of shaft steels with improved corrosion resistances, 1.4305 and 1.7225, were investigated experimentally and numerically in this paper in order to determine some of the material characteristics important for material selection in the engineering design process. Ultimate tensile strength and ...

Improved Iron Phosphate Corrosion Resistance by Modification with Metal Ions

ron phosphate coatings have found a wide range of use in the metalI finishing industry as a convenient method for achieving reasonably high levels of corrosion resistance. Flexibility of processing parameters and ease of use are probably the biggest reasons that iron phosphating enjoys its continued popularity. The corrosion resistance of iron phosphate coatings can be dramatically improved by ...

Increasing of Machine Parts Wear Resistance by Nanostruсturing

This paper presents the scientific rationale for the use of a new generation of functionally graded nano-(L = 50-500 nm) based on the Al-N, Ti-N, Ti-C, Al-O and Mo-S nanolayers (l = 1-10nm) on steel to improve durability for operation in extreme operating conditions of parts and units of machines and mechanisms

Tarnish Resistance, Corrosion and Stress Corrosion Cracking of Gold Alloys

Tarnishing, corrosion and stress corrosion cracking (SeC) of gold alloys are related phenomena. They present problems when they occur in gold jewellery, dental gold alloys and electronic devices. They are exploited, however, in the depletion gilding and finishing of gold jewellery; and in the extraction, refining and fire assaying of gold. There is still much that is not known about these pheno...
