关于低温镀黑铬RAYDENT表面处理的相关知识

什么是低温冷电镀 RAYDENT TREATMENT?
低温冷电镀,工件环境温度控制在0°C左右,镀层厚度1u到3u, 膜层以电化学反应方式,沉积于工件表面,不同于普通镀铬镀镍的是,它的膜层可以往工件表面内延深1u的厚度,所以具有超级耐腐蚀性能,比一般镀铬镍要强很多,适合强腐蚀环境下的丝杆、滑轨、花键等的表面处理;随着时间的推移,工件的防锈能力更强;
低温冷电镀,由于膜层是在0度左右环境下完成反应,所以没有普通表面处理的热变形影响,整个膜层一致性好,不会造成普通镀铬的腰形效应,进而对工件的尺寸公差造成影响;
表面黑色,不反光;
如有这方面需求有用户,可联系我司;
"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.
