Solder Alloy and Method for Repairing a Component

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a new nickel-based solder alloy, which includes zirconium and preferably also germanium, and a method for repairing components made from high-performance materials, such as turbine blades. The solder alloy is designed to fill cracks or voids in components without the drawbacks of conventional welding, such as substrate damage or element evaporation, and is especially useful for nickel- or cobalt-based superalloy parts exposed to high temperatures.

Use CasesContent extracted from patent full text and abstract with AI.

• Repairing cracks or voids in turbine blades used in gas or steam turbines.
• Maintenance and refurbishment of combustion chamber components in power plants or aircraft engines.
• Restoration of high-temperature resistant shield elements in turbines and other industrial machinery.
• Repairing nickel- or cobalt-based superalloy components in aerospace, energy generation, or chemical processing equipment.
• Fixing or refurbishing components with directionally solidified or single-crystal structures where traditional welding is unsuitable.

BenefitsContent extracted from patent full text and abstract with AI.

• Allows repair of high-value components without damaging the underlying substrate material.
• Operates at lower temperatures than traditional welding, minimizing risk of substrate elemental evaporation or structure loss.
• Produces strong joints with high mechanical integrity even at elevated operating temperatures.
• Can be tailored to match the crystal structure (e.g., polycrystalline, directionally solidified, or single crystal) of the repaired part.
• The alloy composition can be adjusted to enhance corrosion resistance, mechanical strength, and compatibility with specific superalloys.
• Extends the service life of expensive and critical turbine or engine parts, reducing maintenance costs and downtime.
• Reduces the need for complete replacement of components, contributing to cost savings and sustainability efforts.
