he wide use of nickel coatings is T due to their valuable properties.l-2 Nickel coatings are used primarily for decorative and industrial purposes. The uses of nickel in the decorative field are. numerous including automobile parts, fumiture, general hardware and fasteners, bicycles, as undercoats in low-cost jewelry, sporting equipment, toys, cutlery, lamps and plumbing fixtures. Most of the d...
متن کاملNICKEL RELEASE FROM 304 AND 316 STAINLESS STEELS lN SYNTHETIC SWEAT. COMPARISON WITH NICKEL AND NICKEL-PLA TED MET ALS. CONSEQUENCES ON ALLERGIC CONTACT DERMATITIS
Release of nickel from nickel or nickel-plated metals, is often responsible for allergic contact dermatitis. However, the effect of nickel-bearing stainless steels is not weil known. ln this paper AISI 304, 316 and 430 type stainless steels, as weil as nickel and nickel-plated materials, are investigated. Three tests were carried out: electrochemical tests and leaching experiments in sodium chl...
متن کاملAn Investigation of the Mechanical Properties of a Weldment of 7% Nickel Alloy Steels
Abstract: During the last decade, the demand for natural gas has steadily increased for the prevention of environmental pollution. For this reason, many liquefied natural gas (LNG) carriers have been manufactured. Since one of the most important issues in the design of LNG carriers is to guarantee structural safety, the use of low-temperature materials is increasing. Among commonly employed low...
متن کاملInduced Turán problems: Largest Pm-free graphs with bounded degree
A graph is H-free if it has no induced subgraph isomorphic to H. Let F(D; H) be the family of H-free connected graphs with maximum degree at most D. Let ex∗(D; H) = max{|E(G)| : G ∈ F(D; H)}; this is finite only when H is a disjoint union of paths. In that case, ex∗(D; H) ∈ O(D2 ex∗(D; Pm)), where Pm is the longest path in H. For m ≥ 6, we determine ex∗(D; Pm) asymptotically (with m fixed), sho...
متن کاملZinc-Nickel Electroplate As a Replacement for Cadmium On High-Strength Steels
A need t o find a suitable replacement for cadmium electroplated coatings on mediumto highstrength steels has accelerated the development of economically viable alternatives. This edited version of a presentation at the 30th annual AerospaceIAirline Plating & Metal Finishing Forum examines the development of Australia's Defence Science and Technology Organisation's (DSTO) zinc-nickel electropla...
