농기계 제조의 업그레이드를 주도하는 레이저 클래딩 기술

9월 24, 2021

As the wheat fields wave in the wind, it’s once again harvest season. According to statistics, by 2000, the level of mechanization in China’s agriculture had reached 48%. However, due to manufacturing process and technology limitations, there is still a significant gap compared to developed countries. The performance of key components in agricultural machinery directly impacts the equipment’s service life. The failure of critical wear-resistant parts, such as rotary tiller blades, harvester discs, and soil tillers, not only greatly increases repair costs but also severely affects the working efficiency of agricultural machinery.

Currently, most agricultural machinery repairs are limited to simple disassembly and part replacement. This increases operational costs for agricultural machinery enterprises and restricts the widespread adoption of mechanization in China.

As traditional agriculture transitions to modernity, applying advanced laser technologies in agriculture has become an important trend, with 레이저 클래딩 기술 being particularly noteworthy.

1. 레이저 클래딩 기술 개요

Laser cladding is an advanced surface modification technology. In this process, a predefined cladding path is set, and a high-energy laser beam is used to quickly melt the cladding material and the surface layer of the substrate, forming a melt pool. Afterward, the material rapidly solidifies, forming a metallurgically bonded cladding layer with low dilution. This process not only allows for in-situ repair of mechanical components but also significantly improves the surface properties of the substrate, such as wear resistance, corrosion resistance, heat resistance, and oxidation resistance.

Key Advantages of Laser Cladding Technology
  • Strong metallurgical bond between the cladding layer and substrate
  • Small heat-affected zone in the substrate, effectively controlling deformation
  • Low dilution rate, reducing the cost of expensive cladding materials
  • Precise control over coating thickness
  • Ability to repair specific areas and regions difficult to treat using other methods
2. Practical Applications in Agricultural Machinery

Before cladding repairs can be applied to agricultural machinery components, thorough surface preparation is necessary. Due to the harsh working environment of agricultural machinery, components often accumulate contaminants like dirt, oil, pesticides, and rust, making the repair process more complex than in other industries.

Traditional agricultural machinery repair techniques, such as heat treatment, chromium impregnation, 및 arc spraying, have difficulty meeting the requirements for wear resistance, corrosion resistance, 및 environmental sustainability. With the ongoing development of laser cladding technology, the performance of cladding layers has continuously improved, and academic research has increasingly focused on its application in agricultural machinery repair and enhancement. Laser cladding not only effectively repairs damaged parts but also strengthens the performance of existing agricultural machinery components.

3. Technical Outlook and Future Development

Exploring advanced repair technologies and performance improvement methods for key agricultural machinery components is of great practical significance for enhancing machine performance and extending service life. In the near future, 레이저 클래딩 기술 is expected to be widely applied in the repair and strengthening of agricultural machinery, providing robust technological support for the mechanization of agriculture in China.

As a high-tech enterprise specializing in industrial-grade laser cladding and metal additive manufacturing, 그린스톤-테크 will continue its focus on the innovation and research of high-speed laser cladding technology. By improving processes and enhancing core component performance, Greenstone-Tech aims to provide more comprehensive solutions for the agricultural machinery manufacturing sector, driving the development of agricultural mechanization in China to higher levels.
