Technical measures to solve metal wear or surface scratches by traditional processes
Repair welding + processing: This repair method is one of the most traditional methods for solving metal wear and scratches. Such repair processes have unavoidable repair defects.
The welding process has a thermal stress effect on the metal, which is easy to damage the device twice;
Due to welding accuracy problems, the repaired parts after welding are more difficult to operate during machining or fitter restoration;
The repaired parts are very easy to deform, which affects the operation accuracy of the equipment.
Electrochemical metallizing repair: This process can repair minor defects such as local scratches or surface wear. The biggest drawback of this process is：
The entire surface is brush-plated, it is not easy to operate on the local scratches or defects in the middle part and there is a problem of delamination or poor combination with the original metal material.
The repair process is only for metal wear with a wear depth of less than 0.3mm, and the repairable range is greatly limited.
Carbon nano-coating technical measures to solve various types of metal wear or surface scratches
The application process of carbon nanopolymer materials is very simple and convenient. After the analysis of the operating environment parameters, the repair of wear or scratches is carried out according to a certain construction process. The commonly used repair processes are as follows:
Machining and repairing process: first, use carbon nano-polymer materials to recover the worn or scratched parts, and then use the machining method to dimensionally repair the repaired materials to ensure the shape and position tolerance requirements of shaft parts or other parts;
Repairing process of the corresponding relationship between components: the online repair technology of the worn parts is completed by utilizing the mutual cooperation relationship of the original components during the operation of the equipment. This repair process can maximize the effective matching surface of the two parts, far exceeding the contact surface between the original metal and the metal;
Tooling tool repair process: according to the original design drawing size of the parts or the actual size measured on site, the corresponding repair tooling is made, and the repair of the worn part is completed in accordance with the application characteristics of the carbon nano repair material, which can well guarantee the geometric tolerance of the shaft parts.
Industrial carbon nanopolymer repair technology is similar to a cold welding technology, which has the advantages of excellent compression resistance, corrosion resistance and thermal alternating resistance, as well as high chemical stability and good physical and mechanical properties, which can be firmly It sticks to the metal surface without falling off easily. No high temperature will be generated during the online repair process, which protects the device body from damage and is not limited by the amount of wear during the repair process.
