In the vast industrial landscape, machines and equipment function like precisely working “steel beasts,” while molds and components act as the essential “bones” supporting their efficient operation. However, time and high-intensity use lead to wear, deformation, and other issues, akin to the way worn shoes affect walking efficiency, potentially causing accidents. Fortunately, Greenstone-tech, a trailblazer in laser technology, introduces its self-developed “laser armor” technology, offering machines, machine tools, and countless equipment components an incredibly strong “protective armor” that enhances wear resistance, high-temperature endurance, corrosion protection, and significantly boosts durability—ushering industrial production to new heights.

Лазерлік қаптау технологиясы: The Magic Cure for Machine Parts’ “Old Problems”

In key industrial sectors like metallurgical plants, building materials, and steel mills, cold-working molds operate tirelessly, bearing heavy workloads. However, molds made from cold-work tool steel, after undergoing cold treatment, are prone to deformation. Once deformed, uneven stress distribution causes increased friction and impact, significantly shortening mold life and compromising product quality.

Take refractory molds as an example. This issue once loomed like a “Damocles’ sword” over manufacturers. However, Greenstone-tech’s engineers, with their rich experience and keen insights, identified laser cladding technology as a “miracle cure” for mold problems, capable of addressing these issues at the root.

Laser cladding uses a laser beam as a “magic brush” to precisely coat a surface with specialized powder materials. When the laser hits the powder, it melts instantly, tightly bonding to the surface. After cooling, a robust protective layer forms, seamlessly integrating with the substrate. This coating significantly enhances the wear and corrosion resistance of the part, enabling it to withstand high temperatures—effectively upgrading its performance.

Laser Cladding for Industrial Components

In industrial applications, booster pumps are key equipment that ensures the stable operation of various systems, widely used in industries like petrochemicals, power generation, and water supply. However, key components like the pump’s plunger face severe challenges during high-intensity, high-load operations. These plungers frequently come into contact with corrosive media, causing surface erosion and increased friction, which deteriorates performance and reduces the sealing precision, increasing the risk of leaks. As a result, production efficiency drops, and equipment failure leads to significant economic losses and energy waste.

Traditional repair methods, such as simple welding, can lead to uneven hardness, defects like pores, and potential deformation due to high temperatures. Electroplating forms a protective layer, but it easily peels off over time. Laser cladding, however, brings a solution, much like its use in molds, by creating a durable protective “armor” that addresses common issues like corrosion and wear.

Choosing the Right Materials for Superior Protection

In selecting materials for laser cladding, Greenstone-tech’s engineers meticulously choose components to ensure performance. They selected Cr12MoV steel, a highly cost-effective material known for its excellent performance, suitable for both cold- and hot-working molds. For testing, one batch of steel was heat-treated to achieve a hardness of HRC47, while another was hardened to HRC58–62 for wear testing.

To further enhance protection, nickel-based alloy powder was selected, which forms a deep, complementary bond with the Cr12MoV steel. A 10.6 μm wavelength 1080 fiber laser was used, ensuring precision akin to a surgeon’s scalpel for flawless operation.

Laser Cladding in Action

The process of applying laser cladding is like a fine art. The first step is to slightly roughen the part’s surface, ensuring that the powder adheres better, much like how paint adheres better to a textured wall. During the cladding phase, precision is key. Engineers carefully control the speed and intensity of the laser, “preheating” the part as one would warm up a car on a cold morning, ensuring stability throughout the process. A uniform coating thickness is crucial for achieving balanced protection.

Once completed, the cladded part undergoes microscopic examination. After cladding, the internal structure of the material shows significant improvement, with previously existing gaps and holes disappearing. The coating forms a perfect bond with the steel, significantly improving hardness and wear resistance.

Proven Performance and Effectiveness

After a series of rigorous trials, Greenstone-tech’s laser cladding technology has proven its effectiveness. In a wear test with Cr12MoV steel molds, the surface showed only 1.096 micrometers of wear under 300 grams of pressure—much finer than a human hair. Even under 500 grams of pressure, the wear was significantly lower than untreated molds, showcasing that the service life of molds is drastically extended with laser cladding.

In a large refractory material production company in Zhejiang, mold wear used to be a major issue, leading to frequent production stoppages. After implementing Greenstone-tech’s laser cladding technology, mold life extended significantly, and issues like wear, deformation, and cracking reduced, improving product quality and production efficiency while drastically reducing costs.

Applications in Other Sectors

Laser cladding technology’s application is broad. In petroleum and petrochemical industries, it enhances the performance of booster pump plungers, significantly extending their service life from months to years. In the power generation sector, laser cladding reinforces critical components like valve bodies and water-cooled walls, improving resistance to wear and corrosion.

In aerospace, components like engine turbine blades are reinforced with laser cladding, extending their service life and reducing maintenance costs. In automotive manufacturing, engine parts like crankshafts and cylinder blocks are repaired with laser cladding, increasing their durability and reducing replacement costs. This aligns with the growing emphasis on green manufacturing and sustainability, contributing to carbon reduction goals.
