Market Background：
Compared with high-end manufacturing fields such as industrial machinery, aerospace, and automobiles, agricultural machinery manufacturing always lags behind them. In order to promote the development of agricultural modernization, it is necessary to strengthen the application of laser cladding technology in the repair and strengthening of agricultural machinery. Learn from advanced technological research results in other fields to provide research directions for the repair and strengthening of agricultural machinery. Therefore, in order to improve the reliability of agricultural machinery in complex soil environments, research can be conducted from the following four aspects: in-situ repair; improvement of wear resistance; improvement of corrosion resistance; and improvement of hardness.
After nearly half a century of research, laser cladding technology has accumulated a large amount of experimental data and basic theories in the field of high-end manufacturing. Due to the characteristics of agricultural machinery and the complexity of its work objects, its manufacturing, repair and strengthening methods lag behind the high-end manufacturing field. Therefore, the research and application of laser cladding technology in the repair and strengthening of agricultural machinery started late, and is basically in the primary research stage of coating material preparation technology and wear resistance and corrosion resistance.
In order to realize the promotion and application of laser cladding technology in the field of agricultural machinery repair and strengthening, research can be conducted from the following three directions in the future:
- Learn from the research results accumulated in the high-end manufacturing industry, combined with the actual production conditions of agricultural machinery repair and strengthening, to change the current situation of low agricultural machinery design and manufacturing levels and slow development speed.
- Research and develop new composite material powder suitable for repair and strengthening of agricultural machinery. Based on the existing material system and combined with the characteristics of agricultural machinery, a high-quality cladding material powder system suitable for different working conditions is designed.
- Laser cladding is the result of the joint action of multiple process parameters. Only by selecting the appropriate combination of process parameters can you obtain the best performance cladding coating. Therefore, studying the optimal design of process parameters has very important practical significance.
Laser cladding technology offers several applications in the agricultural industry, particularly in enhancing the performance, durability, and lifespan of various tools and components. Here are some common applications of laser cladding on agricultural tools:
