The essence of marking metals by thermal influence lies in the ability of some metals to change color under the influence of heat. This process is consists of the formation of thin translucent oxide films on the surface of metals and the effect of light interference. Depending on the thickness and composition of the oxide films, during the interference, certain wavelengths are amplified, and we can see different colors or an iridescent film. Titanium and its alloys create bright blue-violet hues, stainless steels - black, green, blue, red, yellow and other shades.
Modern laser marking systems make it possible to control the parameters of heating and obtain a strictly predetermined result.

In the nuclear power industry, zirconium is used as a cladding for nuclear fuel. In 2004, our company, together with TVEL Corporation, developed a laser technology for marking of zirconium shells with barcodes.
This laser marking made it possible to digitize the entire production record, sales and operations of Russian nuclear fuel.
Barcodes, formed on the surface of zirconium shells with lasers, last for 30 years.Get a sample
Engine components operate in extreme conditions: high temperatures, high variable loads, aggressive environments. The marking of these parts is of strategic importance for the safety and development of this industry. Laser makes it possible to mark high-melting alloys of titanium and iron and powder alloys with indelible marking that meets all the requirements. Our customers mark:
- compressor and turbine blades,
- fuel pipelines.
It is important to mark instruments to be used in a medical facility. The marking must be resistant to corrosion during multiple sterilization cycles, be easily readable, and not cause cracks or pores on the surface of the instrument because they can lead to its destruction or the accumulation of pathogenic microorganisms.
Endoprostheses in medicine are usually made of stainless steel and titanium alloys. Laser allows solving two problems:
- marking of parts,
- surface structuring.
The latter feature of laser processing made it possible to increase titanium dental implants success and to establish the production of dental orthopedic components in St. Petersburg.Get a quote
Color laser marking on the surface of metals allows manufacturing of unique souvenirs. Particularly interesting effects can be obtained on products made of titanium and stainless steel.
