Surface treatment of materials is an important component of laser technology that is constantly evolving. It provides the surface layer of parts of pre-specified physical and mechanical properties. Surface treatment combines a number of independent processes: surface heat treatment (annealing, quenching, tempering), surface microroughing and coating, surfacing, sintering, etc. The basis of the methods of laser surface treatment are complex transient physical and chemical processes. Their knowledge, the ability to calculate them, to calculate individual cases, to predict the consequences and results of processing, to implement processes - all this is necessary for specialists in laser technologies.

The discipline "Laser Surface Processing" refers to the cycle of professional and practical training and based on the knowledge acquired by the student in the study of fundamental and professionally oriented disciplines (higher mathematics and its special sections, physics, chemistry, descriptive geometry, engineering and computer graphics, construction materials engineering, strenght of materials, theory of mechanisms and machines, hydraulics, pneumatics and vacuum technology, materials science, metrology, interchangeability and standardization, machine parts, electrical engineering and electronics, physics of lasers, physics of concentrated energy flows interaction with substance, fundamentals of scientific research and technical creativity, electrophysical and electrochemical methods of material processing). The discipline "Laser Surface Processing" is a theoretical and practical base for students during the implementation of diploma projects and master's theses.

The purpose of teaching discipline: to teach students the principles of analysis and development of laser surface treatment technological processes, which should be the basis for the task of future professional activities.

To achieve the goal at lectures are considered:
- general principles of laser surface processing organization;
- methods of measuring the basic parameters;
- physico-chemical processes in materials under the action of laser radiation;
- processes of absorption, heating, melting, cooling, evaporation;
- thermal processes and methods of their calculation, structural-phase transformations;
- technological circuits of laser processing;
- regularities of the change of surface layers physical and mechanical characteristics after laser processing;
- development of technological processes of laser surface processing;
- technical equipment;

Studying the discipline "Laser Surface Processing" is aimed at forming the students the necessary theoretical knowledge and practical skills in using these effective technologies in industry, designing technological processes of laser surface treatment, forecasting properties of materials and products after laser treatment, applying new principles and approaches to designing machines and appliances.
