TL;DR: In this paper, a preparation method of a graphene/copper composite material is described, which includes the following steps: step 1, weighing copper sulfate pentahydrate, nickel sulfate, citric acid and boric acid; step 2, placing the mixed solution A in a magnetic stirring water bath kettle for heating the mixed mixture A, then adding graphene oxide solution into the mixture B, stirring, and preparing B; step 3, adding sodium hypophosphite solution into B, and finally, performing an accelerated reaction and ultrasound dispersion treatment so as to obtain

TL;DR: In this article, a convex hull-like wear-resistant chrome-plated layer strengthened by spherical particles is presented, which includes the following steps: 1) performing surface pretreatment on a substrate material; 2) screening the spherical particles; 3) putting spherical particles into distilled water and performing ultrasonic dispersion for 1-2h; adding the dispersed spherical particles to a chemical electroplating solution; 4) putting the substrate material after surface pre-treatment obtained in the step 1) into the composite electro-plating liquid; and 5) performing combined current electro

TL;DR: In this article, an electroplating device with optimized temperature field distribution and a plated method was proposed. But the authors did not specify the method of plating the workpiece to be plated.

TL;DR: In this article, an electrodeposition preparation method and application of a convex-hull type bionic texturing chromium coating was described, in which the surface of the coating protrudes like convex hulls, and the surface hulls are in uniform distribution.

TL;DR: In this paper, a method for improving the corrosion resistance of nickel-aluminum bronze was proposed, which comprises the following steps: firstly, grinding and polishing the surface of nickel aluminum bronze, degreasing, pickling and activating, placing the treated nickel-chromium plating solution of which the temperature is 30-40 DEG C and the pH value is 20-35, and electroplating the treated Nickel-Aluminum bronze serving as a cathode to obtain a crack-free Ni-Cr alloy coating, having a smooth surface on the surface
