Fatty acids can corrode metals materials containing oils fats and waxes in contact with copper-based metals will cause the development of green corrosion products (copper soaps Figures 19 and 20) A common problem observed on museum objects made of copper and copper alloys is a characteristic pale green corrosion caused by the reaction between the metal and polish residues (Figure 39)

Liquid phase-sintered tungsten-heavy metals are manufactured from the mixture of metal powders in a single-stage production process during which the components with lower melting points are melted onto those with higher melting points During the binder phase these components form alloys with those that have a higher melting point Even a large amount of the tungsten which has a high melting

Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel an electrolyte fluid and a positively charged workpiece Materials removed from the workpiece stay in the electrolyte fluid Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour

ASTM's corrosion and wear standards provide the appropriate procedures for carrying out corrosion wear and abrasion tests on specified metallic materials and alloys These tests are conducted to examine and evaluate the behavior susceptibility and extent of resistance of certain materials to stress corrosion cracking cavitation erosion intergranular corrosion pitting and crevice

A general but necessarily brief introductory review of the occurrence phenomenology and mechanistic theories of stress-corrosion cracking (in the widest sense of the words) in metals and alloys is provided Those changes which are produced in the surface layers of metals by machining and grinding operations and which could affect the stress-corrosion susceptibility are discussed

What are non ferrous metals? Well read all about them and check out the non ferrous metals list provided in the following article to get a clearer understanding To put it simply non-ferrous metals are all those metals that do not contain any amount of iron and therefore lack two of the most prominent properties of iron – magnetism and corrosion on exposure to oxygen whether atmospheric
