Engineering machinery includes many types such as lifting machinery, earthmoving machinery, transportation machinery, concrete machinery, and railway maintenance machinery. Key components require wear-resistant coating preparation to extend service life, and corrosion resistance must also be considered for equipment operating in coastal or humid environments. Under long-term harsh working conditions, various components of the equipment are prone to damage, such as peeling, spalling, cracking, impact, corrosion, and wear. Therefore, engineering machinery equipment and its components require regular maintenance or repair, resulting in high workloads and maintenance costs. Currently, most engineering machinery components use methods like electroplating and thermal spraying for surface coating preparation, which have limitations such as pollution, low bonding strength, and short service life. Efficient, high-performance surface engineering technologies, remanufacturing repair technologies, and joining technologies hold significant application prospects in the engineering machinery field.
Laser cladding for wear-resistant and corrosion-resistant coatings on surfaces of various-sized shaft components such as hydraulic cylinders, piston rods, and columns; due to low heat input and minimal deformation, it offers unique advantages for surface cladding of components with large aspect ratios.
Laser cladding for wear-resistant hard coatings, erosion-resistant or corrosion-resistant coatings on the inner walls of cylinder components, as well as rapid repair of localized damage on inner surfaces.
Remanufacturing repair of damaged components using conventional laser cladding or manufacturing functional coatings on new component surfaces. Examples include repair of wear-resistant liners, cylinder blocks, connecting part assembly surfaces, valve cones, and valve seats.

Ultra-High-Speed Laser Cladding for Engineering Machinery Piston Rods
Taizhou Shandi Additive Manufacturing Co., Ltd., with the registered trademark "Shandi Additive," is dedicated to the research, development, and production of high-quality metal alloy powders. Serving both domestic and international markets, the company provides standard high-temperature alloy powders, mold steel powders, aluminum alloy powders, nickel-based self-fluxing alloy powders, cobalt-based alloy powders, amorphous alloy powders, brazing powders, iron-based alloy powders, metal-ceramic composite powders, and metal carbide composite powders, among others, for laser cladding alloy coating manufacturing and inspection services.
Piston rods are connecting components that support piston operation, mostly used in cylinders and pneumatic actuators as frequently moving transmission parts. Taking hydraulic cylinders as an example, piston rod surfaces often suffer from plating peeling or scratches due to impact or abrasion, leading to oil leakage and severe surface corrosion, which affects normal operation. Ultra-high-speed laser cladding repair can achieve efficient cladding at 0.8-1.2 m2/hr (depending on coating thickness) for piston rod surface coating preparation, with a single-layer cladding thickness of 0.05-1 mm. Due to low heat input during the cladding process and minimal thermal impact on the workpiece, it can process thin-walled or large aspect ratio components that conventional laser cladding cannot handle, ensuring no deformation. Depending on customer application requirements, hard wear-resistant coatings of different materials such as cobalt-based, nickel-based, and composite materials can be prepared on the component surface, with coating hardness reaching up to HRC65 or higher, effectively controlling cracks.

Ultra-High-Speed Laser Cladding for Mechanical Pins
Taizhou Shandi Additive Manufacturing Co., Ltd., with the registered trademark "Shandi Additive," is dedicated to the research, development, and production of high-quality metal alloy powders. Serving both domestic and international markets, the company provides standard high-temperature alloy powders, mold steel powders, aluminum alloy powders, nickel-based self-fluxing alloy powders, cobalt-based alloy powders, amorphous alloy powders, brazing powders, iron-based alloy powders, metal-ceramic composite powders, and metal carbide composite powders, among others, for laser cladding alloy coating manufacturing and inspection services.
Pins can be used for static fixed connections or relative motion with connected parts, primarily employed at the hinge points of two components to form a hinge connection. Once a pin fails due to wear, it can cause shaking in the working state of equipment components or even affect the direction of movement. The loss and failure of pins mainly result from wear. Applying ultra-high-speed laser cladding technology to mechanical pins can effectively increase surface hardness (HRC65 or higher) and wear resistance, significantly extending the service life of pins, reducing the likelihood of connection failure between equipment components, and improving the operational efficiency of the equipment.
