The traditional surface treatment technique includes plating,electroplating and etc., which have disadvantages such as poor adhesive and polluting the environment.However,The new technique--ion plating overcomes all these shortcomings. It can make high quality coating such as TiN, TiNC, TiC, ZrN, TiAlN, CrN and many others in noun-pollution process. These coatings have both good decorative and mechanical features that are applied in both industry-used and daily-used products.
Plating is an advanced vacuum coating technology which includes arc deposition, hollow cathode depositioe-beam deposition and others techniques. The arc deposition technique applied by Sinoarc is a method of highest commercial value.
The coating process of arc evaporation is that the coating material , pure titanium block for example, is evaporated by electric arc and turned into plasma in vacuum chamber. Then the plasma is accelerated by electric field and reacts with inlet reactive gas (N2 for example). Next, the compound ( TiN etc.) deposits on the workpieces and makes a thin film.
Changing coating material or reactive gas so that different films can be made to meet customer's needs.
TiN for color of golden, TiC for gun black, ZrN for brass and TiCN for rose gold and etc.
Compared
With
Others vacuum coating methods, arc evaporation has a very high ionization rate which results in high quality coating.It is also a very versatile method which can make many kinds of films and easy to adjust coating data in process.The arc evaporator can be placed in either horizontal or vertical way, so large coating systems can be easily made by adding more evaporators.
As coating work cycle is short and coating system will be very large, arc evaporation technique is the most efficient vacuum coating method that becomes the first choice of industry production. The key technology in manufactory of arc coating systems are onvacuum, electric power(especially bias power), electric control, evaporator and coating art.
As a coating system producer, the main advantages of Sinoarc are power and control part, along with evaporator and coating art. Our systems for tool coating and Zr coating are able to compare with products of any other system producers. The high-qualified film we offer for bathroom hardwares is standing at the leading place in the field.
Fields of application: Arc deposition is applied in two main fields:
Tool coating: Cutting tools made of high speed steel or carbide alloy will have a better cutting performance and longer life after coating. Mould's life can also be promotted after coating.
Decorative coating:
Architecture: Bathroom hardware(faucet),locks, door handles, furniture
Watch Industry: watch cases, watch bands,watch hands
Other Hardwares: hardwares for leather, spectacle frames, stainless steel
Large Workpieces: stainless steel sheet
