Debido a su funcionamiento prolongado en entornos fluviales y marinos, muchos componentes de plataformas de perforación en alta mar, buques y grandes grúas marinas sufren corrosión y desgaste severos, lo que requiere tratamientos protectores y reparaciones. Para las piezas de tipo eje que necesitan recubrimientos resistentes al desgaste y la corrosión en grandes superficies, es fundamental contar con tecnología de procesamiento de superficies de alta eficiencia. Además, algunos equipos de potencia sufren fallas por desgaste localizado, como cuando aparecen limaduras de hierro o impurezas en el sistema de lubricación, o cuando se produce una baja temperatura o presión de aceite durante el arranque del motor, lo que provoca abrasión entre el cojinete y la superficie del eje. Estos daños localizados requieren revestimientos y reparaciones de precisión, lo que hace que los métodos de restauración robótica automática y flexible sean ideales.

Para abordar los problemas de desgaste y corrosión en componentes mecánicos marinos, la tecnología de reparación y remanufactura mediante revestimiento láser ofrece una solución altamente eficaz. El revestimiento láser satisface tanto las necesidades de recubrimiento de grandes superficies como las de reparación localizada, y se aplica ampliamente en motores diésel marinos, turbinas de gas marinas, turbinas de vapor, hélices, estructuras de casco y otros equipos marinos críticos. Esta avanzada tecnología de ingeniería de superficies mejora significativamente la durabilidad de las piezas, reduce los costos de mantenimiento y prolonga la vida útil de la maquinaria naval y de ingeniería oceánica.

Laser cladding technology is widely applied in ship component restoration and delivers significant performance improvements. Key applications include:

Propeller repair: Precise control of laser power (2–5 kW) and spot diameter (0.5–2 mm) enables accurate restoration of hydrodynamic performance.
Engine cylinder liner scoring: Alloying elements such as chromium (Cr) increase corrosion resistance and hardness of the cladding layer.
Shaft corrosion pit repair: Laser cladding forms a 0.5–3 mm coating, achieving post-repair surface roughness of Ra 0.8–1.6 μm.
Gear repair: Maintaining a scanning speed of 5–10 mm/s increases tooth surface hardness and contact strength, extending gear life.
Valve sealing surface repair: Cobalt-based alloy powders allow the sealing surface to withstand 10–20 MPa, ensuring sealing reliability.
Chain wear repair: Introducing WC reinforcement phase on the surface extends wear life by 2–3 times.
Pump housing repair: Adjusting pulse frequency (20–50 Hz) ensures strong metallurgical bonding between the cladding layer and the substrate.

Process control guidelines:

Preheating treatment: Heat alloy steel parts to 150–250°C to reduce thermal stress and prevent cracking.
Post-heat treatment: Temper high-strength steel components at 550–650°C to eliminate residual stress and improve mechanical performance.

Through optimized material selection and process control, laser cladding significantly enhances wear resistance, corrosion resistance, and service life of ship components. This advanced technology is suitable for critical parts such as propellers, cylinder liners, shafts, gears, valves, chains, and pump housings, offering reliable marine equipment remanufacturing and long-term durability.

Recubrimiento láser ultrarrápido
Used for high-efficiency deposition of wear-resistant and corrosion-resistant coatings on shaft components of various sizes, including offshore platform columns, steam turbine rotors, and drive shafts. This advanced process enables rapid cladding of large components, and due to its low heat input and minimal distortion, it also offers significant advantages for heat-sensitive materials and small-size parts.

Internal Wall Laser Cladding
Designed for applying wear-resistant hard coatings, erosion-resistant or corrosion-resistant coatings on internal surfaces of components. It enables rapid restoration of localized internal surface damage and laser cladding in narrow or confined spaces that are difficult to access with traditional processes.

Conventional Laser Cladding Repair
Applied for remanufacturing damaged parts or creating functional coatings on new components. Typical applications include laser cladding repair of corroded and worn cylinder heads, engine blades, and other critical machinery parts, significantly improving durability and service life.

Ultra-High-Speed Laser Cladding Repair for Drive Shafts
Drive shafts commonly fail due to damage, wear, and deformation, which can cause mechanical malfunctions and disrupt normal equipment operation. Ultra-high-speed laser cladding technology provides an efficient and precise solution to these issues by enabling targeted localized cladding. This enhances the hardness and structural strength of bearing areas, significantly improving durability and service life.

The cladding thickness can be accurately adjusted from 0.05–1 mm, achieving a processing efficiency of approximately 0.8–1.2 m²/h depending on the layer thickness. With extremely low heat input, the process minimizes thermal distortion while producing dense coatings with strong metallurgical bonding.

In addition, ultra-high-speed laser cladding reduces material consumption and post-processing requirements, delivering unmatched advantages in cost efficiency, processing speed, and thermal impact control. This makes it an ideal technology for high-performance, long-lasting drive shaft restoration and surface reinforcement.
