Lasers are used in almost any industry: from automotive to precision electronics.  Lasers allow you to literally "print out" a detail of any size and complexity. This kind of technology  is  similar to printing out in a 3D printer.  Such a powerful and elegant  engine requires skillful handling, accounting for a huge number of physicochemical parameters of fused metals.

The technology of laser additive production  itself  is becoming an interdisciplinary science.

About department

Department of Laser Technologies of KNRTU-KAI was founded in 2013. It specializes in preparing students in bachelor's and master's programs in 12.03.05 "Laser Technology and Laser Technologies" specialty.

Areas of research

The department specializes in conducting fundamental and applied research in additive laser technologies. Numerical modeling of the processes accompanying additive laser technologies (Direct metal deposition, DMD), allows to reveal regularities between the conditions for coating of application and its physical and mechanical properties. More so, the scientific laboratories are equipped with the newest experimental facilities and allow to verify these calculations. Thus, the department carries out research and optimization of the installations and modes of operation of DMD-systems to obtain geometric surfaces with given chemical, physical and mechanical properties.

Equipment

The KNRTU-KAI research team has a set of the most advanced equipment for research in laser technologies, including additive technologies. Laser technological installations (produced not earlier than 2014) for laser cutting, welding, strengthening, traditional powder laser surfacing and supersonic laser surfacing of the well-known IPG Photonics company allow to conduct research of physical-chemical and technological processes in conditions that are as close as possible to actual production.

There is an original schlieren system with high-speed registration of shadow images to diagnose for gas and powder flows, along with a PIV system and a three-component laser Doppler anemometer Dantec Flow Explorer.

The spatial temperature distribution in the melt bath is studied using the FLIRSC7700 BB thermal imaging camera and an original multi-wavelength pyrometer with a high spectral and temporal resolution.
