Ceramic Coating On Aluminum
The advantages of approaches 1 and 2 are obvious. The invention relates to a composition for forming a heat insulating ceramic coating on a metal said composition comprising in by weight.
One of the main processes used in the ceramic coating of aluminum is known as micro arc oxidation mao also known as plasma electrolyte oxidation peo.
Ceramic coating on aluminum. Then pressurized gas is used to spray molten ceramic material onto a surface producing a ceramic coating with a high level of cohesive bonding. There are a wide range of ceramic coating materials that can be applied to metal components in order to enhance their functional properties. Anodizing processes in type iii hard coating a bath of sulfuric acid with added powdered aluminum is chilled down to approximately 30 degrees f and used as the electrolyte.
There are five types of itc ceramic coatings including itc 148 itc 100ht ceramic coating itc 213 ceramic coating for metals itc 296a ceramic top coating and itc 200 ez ceramic repair. Common applications include polished brushed raw and anodized aluminum used in architectural automotive industrial consumer goods and more. Ceramic composite coatings series 100 ceramic composite coatings for aluminum magnesium substrates.
10 50 of potassium silicate 10 50 of silica 5 40 of inorganic filler 1 25 of ceramic fibres 2 40 of water 2 20 of hollow microparticles 0 5 of surface active agent. Before applying a coating it is important to ensure compatibility between the ceramic material and the metal surface. Under an applied electric waveform the parent metal your work piece combines with elements in an acid based electrolyte to form a protective layer of ceramic.
Ceramic coat the low cost standard aluminum engine block. Cerakote clear aluminum mc 5100 has been specifically engineered for performance on all common alloys of aluminum including magnesium alloys. It is the purpose of this paper to present the merits of option 3 the ceramic coated aluminum cylinder bore from the standpoint of low weight cost and tribological effectiveness.
Most ceramic coatings are electrically nonconductive making them excellent insulators have a significantly higher level of abrasion resistance than most metals and are capable of maintaining their integrity under severely elevated temperatures. Much of this compatibility depends on thermal expansion properties as having expansion rates that differ too greatly can cause a coating to crack when it is being cooled after application. Endura s ceramic hard coatings are created with a proprietary immersion based spark deposition process which transforms the outermost layer of your aluminum or magnesium substrate into a ceramic oxide.
Each has known advantages and disadvantages.
