Lee Spring's expertise in materials from steel through stainless steel, plastic composite, Elgiloy (cobalt-chrome nickel) and many other nickel and
cobalt alloys such as Inconel, Nimonic, Hastelloy, Monel, also phosphor bronze and beryllium copper, will be available to engineers whatever their application or area of interest.
This time, new
cobalt alloys were developed to replace the platinum.
Among the topics are the creation of a new class of nanocomposite coatings with increased crack resistance and hardness using innovative beam technologies, modeling the spark plasma sintering of powder materials by the finite element method, the selective laser melting of three-dimensional structures produced from heat-resistant
cobalt alloys, and determining the true temperature in the selective laser melting of metal powder using an infrared camera.
The
cobalt alloys also present interesting magnetic properties making them candidates for disk storage media.
The high-cost nickel and
cobalt alloys are used only where they are needed in the tooling; lower stressed sections of the tool can be made from more conventional tool steels.
Cobalt alloys are erosion- and corrosion-resistant metals designed to retain high strength during long-term exposure to high temperatures.
Sandvik Materials Technology, a world-leading manufacturer of high value-added products in advanced stainless steels and special alloys, and ThyssenKrupp VDM, one of the world's leading suppliers of nickel and
cobalt alloys, titanium and other high-performance materials, have announced that they have agreed on a cooperation on the production and sale of zirconium products.
Lack of information on manufacturing
cobalt alloys and uncertain limits of high speed domain found in bibliography for superalloys--from 200m/min (Schultz) to 400m/min (Denkena et.
The remaining chapters address passivity, iron and steel, effect of stress, atmospheric corrosion, corrosion in soils, oxidation, stray-current corrosion, cathodic protection, metallic coatings, inorganic coatings, organic coatings, inhibitors and passivators, treatment of water and steam systems, alloying stainless steels for corrosion resistance, copper and copper alloys, aluminum and aluminum alloys, magnesium and magnesium alloys, nickel and nickel alloys, cobalt and
cobalt alloys, titanium, zirconium, tantalum, and lead.
Both the SAC 305 and
cobalt alloys exhibited no deterioration in solder attachment integrity after 1,000 thermal cycles (Figure 1).
The Berry amendment prohibits the DoD from acquiring certain goods --including some steel alloys, nickel and
cobalt alloys, and titanium--unless made or reprocessed in the US or a "qualifying country." Yet those qualifying countries can source where they like.
meganewtons per sq m, or 7 kilograms-force per sq mm. Cobalt alloys of the Co-Cr-Ni-Mn system, which contain up to 50 percent Co (deformable cobalt alloys), exhibit high resistance to thermal fatigue and can be worked under pressure. Cobalt alloys called stellites (30 percent Cr, as well as W, Si, and C) are used for hard-facing of machine tools and parts (without subsequent heat treatment) to increase their wear resistance. As a basic or alloying element, cobalt is one of the magnetic materials.
