什么是低溫冷電鍍 RAYDENT TREATMENT?
低溫冷電鍍，工件環(huán)境溫度控制在0°C左右，鍍層厚度1u到3u, 膜層以電化學反應方式，沉積于工件表面，不同于普通鍍鉻鍍鎳的是，它的膜層可以往工件表面內(nèi)延深1u的厚度，所以具有超級耐腐蝕性能，比一般鍍鉻鎳要強很多，適合強腐蝕環(huán)境下的絲桿、滑軌、花鍵等的表面處理；隨著時間的推移，工件的防銹能力更強；
低溫冷電鍍，由于膜層是在0度左右環(huán)境下完成反應，所以沒有普通表面處理的熱變形影響，整個膜層一致性好，不會造成普通鍍鉻的腰形效應，進而對工件的尺寸公差造成影響；
表面黑色，不反光；

"RAYDENT treatment" is a special surface treatment technology to form an alloyed surface of metallic materials by means of electroplating.
Using an electrochemical reaction at a temperature below 0°C, which is different from ordinary chemical reactions, chrome ceramic particulates of about f1 mm or smaller in size are precipitated in large number. Part of their coating forms an alloy-like diffusion layer (about 1 mm) in the bulk of the metallic material, which is a great feature of this treatment. Therefore,
(1) The RAYDENT coating and the base metal are completely integrated, so the coating is semi-permanent and will not be separated (exfoliated). The alloyed metallic surface goes through a stable period to become stainless and forms a continuous protective rustproof strong film with the still outer oxide ceramic layer (about 1 mm).
(2) Using the property of (1), various high polymer resins (for example, organic glass solutions, fluorocarbon resins, and highly functional resins) are impregnated in numerous pores in the RAYDENT coating. Such a material can present any physical and chemical properties (mechanical, electrical, chemical, optical, vacuum, and thermal shock etc.) almost permanently without yielding to intense mechanical deformation in all industrial areas from outer space to deep sea. This will bring about a revolutionary progress in industrial engineering, so we call it "RAYDENT Nucreal Advanced Technology."
On the other hand, this unique RAYDENT coating give an innovative interpretation to Faraday′s law of electrolysis. Coulomb′s law forms the theoretical basis of electroplating technology and JIS standards, based on the proportionality of electric current, while the RAYDENT coating is an unprecedented technology unique in the world that has proven a rust inhibiting theory (the infinite dispersion potential theory) of very thin films from the potential difference side.
The greatest contribution of this technology so far is found in the Japanese high-tech industries represented by semiconductors. Iron and steel materials are indeed liable to rust, but are easy to machine and available in various types. This technology has made it possible to use such rust-prone materials and has led the high precision electronic equipment industry, which is necessary for semiconductor manufacturing, to the highest position in the world.
