Stellite alloys are a family of completely non-magnetic and corrosion-resistant cobalt alloys of various compositions that have been optimised for different uses. Stellite alloys are suited for cutting tools, an example is Stellite 100, because this alloy is quite hard, maintains a good cutting edge at high temperature, and resists hardening and annealing.
Chromium carbide is useful in the surface treatment of metal components. Chromium carbide is used to coat the surface of another metal in a technique known as thermal spraying. Cr 3 C 2 powder is mixed with solid nickel-chromium. This mixture is then heated to very high temperatures and sprayed onto the object being coated where it forms a ...
Coating mechanical parts can help with problems of corrosion, adhering, high-temperature and mechanical wear thus reducing unplanned repairs and loss of production. The features of PCC coatings are: obtaining protective layers with high adhesion strength on parts and products made of various engineering materials including metal and non-metal ...
Paint remover is applied to an aircraft's landing gear during an inspection looking for cracks in the aluminum. Paint stripper or paint remover is a chemical product designed to remove paint, finishes, and coatings, while also cleaning the underlying surface. Chemical paint removers are advantageous because they act on any kind of geometry and ...
The removal of oxidization (tarnish) from metal objects is accomplished using a metal polish or tarnish remover; this is also called polishing. To prevent further unwanted oxidization, polished metal surfaces may be coated with wax, oil, or lacquer. This is of particular concern for copper alloy products such as brass and bronze. [2]
The home remedies vary in effectiveness and carry the risk of skin irritation and abrasion as a result of excessive scrubbing, plus eye irritation if allowed to drip or run into the eye. Some of the more common home remedies include: bleach, ammonia, acetone, and rubbing alcohol. The following are risks of the common removal methods: Acetone
Stainless steel (chromium, nickel) AL-6XN; Alloy 20; Celestrium; Marine grade stainless; Martensitic stainless steel; Alloy 28 or Sanicro 28 (nickel, chromium) Surgical stainless steel (chromium, molybdenum, nickel) Zeron 100 (chromium, nickel, molybdenum) Tool steel (tungsten or manganese) Silver steel (US:Drill rod) (manganese, chromium, silicon)
Some of them, including titanium carbide and tungsten carbide, are important industrially and are used to coat metals in cutting tools. [ 3 ] The long-held view is that the carbon atoms fit into octahedral interstices in a close-packed metal lattice when the metal atom radius is greater than approximately 135 pm: [ 2 ]
