The invention discloses a method for stripping a metallic thin film attached to the surface of a material, belonging to the technical field of surface treatment of materials. The method comprises the following steps that: a metallic thin film coated on the surface of a material is connected to a circuit and used as a negative electrode; the metallic thin film is coupled with a counter electrode, then driven by an external power supply and performed a brine electrolysis process in an electrolyte solution, so that a hydrogen evolution reaction is implemented on the metallic thin film, wherein the electric current density of the negative electrode is 30-3000 amperes / square meter, the molar concentration of an electrolyte is 0.0001-1M, and the temperature of the electrolyte solution is minus 5-90 DEG C; the metallic thin film is stripped from a matrix under a mechanical action caused by precipitated hydrogen, then a matrix material and the stripped metallic thin film are respectively collected; the electrolyte solution attached to the surfaces of the matrix material and the stripped metallic thin film are scoured off by water so as to obtain a matrix material and a metallic thin film bunch which are separated from each other. The method disclosed by the invention has the advantages of good metallic thin film stripping effect, small required equipment investment, simple production and maintenance, cleanness and speediness; and by using the method, the damage to a stripping process on the matrix material is avoided or inhibited.

The invention provides a production technology method of a low content alloy ultrahigh hardness wear-resistant steel plate, belonging to the field of metal material; the production technology method is characterized in that: enhanced control cooling and once more off-line heating quenching process routes are carried out to the rolled steel plate; especially, enhanced control cooling is carried out to the rolled steel plate, the cooling starting temperature is 850-780 DEG C, the cooling speed is controlled to be 15-30 DEG C / s, and the final cooling temperature is 350-550 DEG C; then the temperature is naturally cooled to room temperature, and the steel plate is heated for 10-120min and is quenched to be at room temperature, and the quenching temperature is 950-900 DEG C; 100-400 DEG C tempering is carried out to the quenched steel plate, and the tempering time is 20-180min. the hardness of the wear-resistant steel plate produced by the invention is more than 500HB and the total alloy amount is less than 6 percent; therefore, the production technology method has the advantages of low cost, high additional value, stable process and easy realization.

A process for plating Galfan alloy on the surface of steel wire includes such steps as paying off, degreasing, pickling, water washing, preplating in electrolytic liquid prepared from zinc sulfate, catalyst GD-L and water, baking, hot dipping for plating, vertically leading out, wiping, forced cooling and winding. In said hot dipping step, an internal heater made of anticorrosion alloy pipe is used.

The invention discloses a copper plating device adopting an external tank for dissolving electrolytic copper and a copper plating technique thereof. By adopting an insoluble anode in the plating tank, phosphorus powder, copper powder and insoluble impurities can be effectively prevented from being generated by the anode, a high-purity electroplating solution is prepared, and the corrosion resistance of a clad layer and the quality of an electroplated product are improved; metallic copper is supplemented from the outside, no anode mud or copper powder or phosphorus powder is generated, the utilization rate of the metallic copper can be effectively increased, and electrolytic copper is cheaper than phosphorous copper and active copper oxide powder; meanwhile, the concentration of copper ions can be controlled, the content of copper sulfate is prevented from being increased, and the quantity of supplemented sulfuric acid can be decreased; the voltage loss of the anode is small, and the whole insoluble anode can conduct electricity extremely uniformly so that the distance between a cathode and the anode can be decreased to a large extent, the voltage of the plating tank can be effectively reduced, and energy consumption can be reduced; and the current efficiency difference between the cathode and the anode is avoided, the problems that the content of the copper sulfate is increased and sulfuric acid consumption is high are solved, maintenance is easy, and the environmental friendliness is better.
