Anticorrosive wearable electrodeposit clad layer of Ni-W-P ternary alloy and manufacturing technique and electroplate liquid thereof

Abstract

The invention relates to an anticorrosive wearable electrodeposit clad layer of Ni-W-P ternary alloy and manufacturing technique and electroplates liquid thereof, which takes the nickel sulfate, sodium tungstate, phosphate as the main material, electrically depositing the Ni-WP amorphous mixture of amorphous or nanocrystalline alloy coating. The characteristics of the electroplate technique are following: corrosive solution is very small, the entire production of the use of cleaner production, less emissions, in line with the requirements of sustainable production. W of the coating for the content of 1-45wt%, P content of 0.1-5wt%, nickel is the residue. The plating layer is bright and dense; the hardness is 400-1100Hv, which is resistant to acid, alkali, salt and hydrogen sulfide corrosion, wear resistance is better than or equivalent to chrome plating, can not only replace decorative chromium or hard chromium is widely used, and can be used for oil field exploration equipment to deal with wear-resistant anti-corrosion.

Description

technical field

[0001] The invention belongs to the technical field of electrochemistry and metal surface treatment, and relates to a Ni-W-P ternary alloy anti-corrosion and wear-resistant coating obtained by electrodeposition in an aqueous solution, an electrodeposition production process and an electroplating solution composition. Background technique

[0002] Chromium plating has been widely used in various fields for a long time due to its advantages such as high hardness and beautiful color. But as we all know, chromium (Cr 6+ ) Salt is highly toxic, seriously pollutes the environment, destroys the ecological balance, and harms the health of the staff. It is one of the most serious environmental pollution and one of the most harmful heavy metals to human health; The disadvantages of the plating solution, such as high corrosiveness, poor dispersion ability, low current efficiency, and difficult disposal of the three wastes, have begun to face the fate of being eliminate...
