Laser Marking Machines for High-Temperature Materials|Laser Marking on High Temperature Alloys

It provides a professional solution to the problem of the oxidized layer turning black and the mark being unclear after laser marking of high-temperature alloys.By optimizing laser parameters and combining pre-processing and post-processing techniques, the company has effectively solved the problem of oxidation of nickel-based alloys, titanium alloys and other materials in high-temperature environments.The company provides complete technical guidance, from equipment selection to parameter adjustment, to help users achieve clear, long-lasting markings that meet the stringent requirements of the aerospace and automotive industries.

High-temperature alloys are prone to forming an oxide layer during the laser marking process, which can result in unclear markings and a reduction in contrast.This problem is particularly evident in nickel- and cobalt-based alloys, especially in parts that must be used at high temperatures for long periods of time.

Solving this problem requires adjusting the laser's parameters based on the material's composition.For instance, for Inconel alloy, a low frequency (20-30 kHz), short pulse (100-150 ns) setting, with moderate power (30-50 W), can effectively reduce the size of the heat-affected zone.Before laser engraving, the surface must be pre-treated with a mixture of alcohol and dilute hydrochloric acid to remove any residual oxidation from the production process.

Post-processing of the oxide layer is also an important step to be taken.We have tested that if the marked workpiece is immersed in a 10 % nitric acid solution for 15-20 seconds and then cleaned in an ultrasonic cleaner, the corrosion resistance of the marked area can be significantly improved.For components that must withstand high temperatures for long periods of time, we recommend that after cleaning, they be coated with a nanoscale layer of aluminum oxide, which after 300 hours of testing at 800 ° C, still retained 90 % of its original clarity.

In practical applications, the markings on a turbine blade of an aircraft engine remained legible after 1000 ° C / 200 hours of heat cycling.The technology has already been successfully applied to permanent labeling of critical components such as turbine disks and combustor assemblies. It has helped manufacturers improve their ability to trace products, and reduce the risk of quality control problems resulting from failure of the labels.
