With the development of global trade and shipping industry, the importance of ship port machinery forgings in the field of logistics and transportation has become increasingly prominent. These forgings are not only required to withstand harsh working conditions, but also to ensure a high level of safety and durability. In order to improve the performance and service life of mechanical forgings in ship ports, surface treatment technology plays a vital role.
Surface treatment technology refers to the modification or protection of the surface of the object through a series of chemical, physical or mechanical methods to achieve anti-corrosion, wear-resistant, beautiful and other purposes. For ship port mechanical forgings, the main role of surface treatment technology is to enhance its corrosion resistance, improve wear resistance and appearance quality, so as to extend its service life.
Surface treatment technology includes a variety of methods, such as chemical treatment, electroplating, heat treatment, etc. Suitable surface treatment technology can be selected for different use needs. Chemical treatment is to remove the dirt and oxide on the surface of the forging through pickling, passivation, soaking and other means to improve its anti-corrosion performance. Electroplating is the deposition of a layer of metal or alloy on the surface of the forging by electrochemical methods to improve its wear resistance and aesthetics. Heat treatment is to change the metallographic structure inside the forging through heating, insulation and cooling steps, so as to improve its hardness and wear resistance.
In order to ensure the quality of the surface treatment, it is necessary to carry out strict testing of the processed forgings. First observe the appearance, check whether the surface is smooth, no obvious defects. Secondly, the hardness is tested to ensure that the processed forgings meet the expected hardness requirements. Finally, the corrosion resistance and wear resistance of forgings are tested by means of salt spray test and wear resistance test.
In the process of testing, once the quality problem is found, the corresponding remedial measures should be taken in time. For appearance defects, can be repaired or reprocessed; For the problem of insufficient hardness or excessive treatment, repair welding, grinding and other methods can be taken to repair; For the case that the corrosion resistance or wear resistance does not meet the requirements, the surface treatment should be re-performed, and the process parameters should be adjusted to ensure that the quality is up to standard.
In short, the surface treatment technology of ship port mechanical forgings has an important impact on its performance and service life. Through reasonable surface treatment technology and strict testing process, the corrosion resistance, wear resistance and appearance quality of ship port mechanical forgings can be significantly improved, and their service life can be extended. Therefore, in actual production, we should pay full attention to the application and development of surface treatment technology, constantly optimize the process flow and parameters, and improve production efficiency and quality level.
