3. Lectrofluor (Coating method and material)
Previous definition(15 Nisan 2011 11:47)(better):
The properties that can be easily achieved using polymoer organic coatings are dielectric, chemical corrosion, and radiation resistance; in addition, special organic coatings can be used with food and pharmaceuticapl plications in compliance with regulations of the U.S. Food and Drug Administration. All coatings are proprietary, since they are new developments, and specific nomenclature (601, 604, 615, 611, etc.) is used for identification.Coatings can be applied by spraying, by dipping. or by an electrostatic powder process. In most cases, a curing temperature will be in the range of 300-750°F will achieve maximum surface hardness and minimize porosity. Polymer coatings normally range from 0.001 to 0.015 in. in thickness.
Salt spray resistance of these coatings is excellent: approximately 2000 hours (6 years in the atmosphere). The chemical resistance is the main property of the 60 1 coating. which can withstand strong acids and alkalies at temperatures up to 2000°F. The 604 material has similar resistance but can be utilized in food applications. The 615 is a tough. durable coating (D-80 durometer) that can withstand temperatures from -400 to 500°F and can also be used i n food applications. The 61 1 coating, which has good release characteristics, also is used in applications in the baking industry and comes in a variety of colors.

NEW:
Lectrofluor polymer and copolymer coatings from General Magnaplate Corp., Linden, NJ, provide corrosion resistance in hostile environments at both high and low temperatures. Lectrofluor 601, for example provides chemical resistance in scrubbers, chemical pumps (shown here), and energy-related applications. Other coatings are useful in food and pharmaceutical processing, marine, and chemical processing.

8. Magnagold (Coating method)
Previous definition (15 Nisan 2011 11:41)(better):
Since the introduction of titanium nitride to the industrial sector oating companies have been offering this service without sufficient knowledge of its engineering properties. The coating was known to be extremely hard, and it was being applied to cutting tools exclusively. One of the unique features of the titanium nitride process is the uniformity of the coating. This is critical for many applications involving missile, computer, and semiconductor applications. Other excellent applications are found in the plastic extrusion industry (which utilizes the superior release properties in molds and dies); the medical industry (for coating delicate surgical instruments, and preventing solder adherence when special heat treatments are employed in the complex multistep process). In this Magnagold process, a uniform coating. held to within a few millionths of an inch thickness, can be applied safely to even the most critical, closest tolerance parts via special cleaning fixturing mechanisms and techniques that enable the part to be rotated 360" while traveling throught he vapor stream. Because the parts to be coated are rotated both radially and axially within the unique ion bombardment chamber, there are no restrictions on shapes. In addition, all surfaces, except clamp and fixture areas, are uniform in coating thickness. Normally, the thickness ranges from 0.00003 and 0.0002 in., with final determination being edge sharpness and/or wear. (Load life is the ultimate criterion for the final decision.) Since the condition of the substrate surface is a key element in the effectiveness of any physical vapor deposition (PVD) process, General Magnaplate has engineered an exclusive, proprietary predeposition surface preparation. A combination of specialty designed equipment and chemical cleaning techniques prepares the component surface to assure permanently interlocked anchoring of the “coating.” Conventional vapor deposition applicators are not equipped with the extensive facilities that permit the meticulous care and attention required in the precleaning phase of the process. The parts are mounted on a specially designed cylindrical fixture, and then the entire work cylinder enters the vacuum chamber. A vacuum (1 X torr) is achieved, after which the system is purged with argon gas as an additional cleaning step. Titanium metal (99.9%) is then vaporized by a plasma energy source. This is followed by the precise introduction of nitrogen, the reactive gas, into the chamber. The parts to be coated are cathodically charged by high voltage (DC), thereby attracting accelerated ions of titanium. Simultaneously, they combine with nitrogen to produce the tightly adhering, highly wear-resistant titanium nitride PVD coating.

NEW:
They were told of Magnagold,a titanium nitride, The coating process The Magnagold process sequence starts with chemically cleaned components that are stored within a dry box that is maintained in a controlled atmosphere.
The Magnagold process creates a dense, smooth, hard (equivalent to 85 RC) 0.4 mm (15 micro-in.) coating on nearly any surface. The non-stick coatings increase operating life of the cutting surface.

9. Magnaplate TCHC (Coating method)
Previous definition:
This surface-enchancement, precision anodizing technology was developed to solve a problem with a geometrically complex electronic component. This part required thermal conductivity and it had to be electrically insulative.
(Advanced Machining Technology Handbook,James Brown, p.431)
NEW(better):
A variation of the anodizing process available from General Magnaplate Corp. produces thermally conductive but electrically insulated surfaces on aluminum heat sinks. Called Magnaplate TCHC, the new method bubbles purified and filtered air through sulfiric anodizing electrolyte during electrolysis so fresh electrolyte continually circulates. This technique forces cooled electrolyte to the surface, absorbing all the electrolytic energy being introduced to the constantly oxidizing outer layer of aluminum. According to Walter P. Alina, vice president — technical, Magnaplate also developed a new electrolyte for the TCHC process that increases penetration from 50% to 75%. "This was considered a breakthrough," says Alina.

10. Magnaplate SNS (Coating method)
Previous definition:
this surface provides superior wetting resistance to any metal. A serious problem in manufacturing assemblies is splatter from solder and brazing rods and welds sticking to the fixture or other places, where it iş not wanted. Magnaplate SNS creates an ultra-hard surface, close to Rc 80, from 0.0003 to 0.0010" thick, which eliminates most tedious and costly cleaning.
(Advanced Machining Technology Handbook,James Brown, p.431)
NEW (Definitions have very close meanings):
Magnaplate "SNS", a protective coating which prevents most molten metals from adhering to its surface is described in a brochure from General Magnaplate Corp., Linden, NJ Engineering data explore attributes of the coating, which creates a totally non-solderable surface, by providing wetting resistance to all solderable and weldable metals; adds an ultra-hard surface; slashes post-production clean-up and maintenance costs; offers a thickness under 0.0003 inches.
