“…Rozwój systemów laserowych, które generują ciągi impulsów o czasach trwania rzędu nano-, piko-lub femtosekund, rozszerzył ich zastosowanie w dziedzinie budowy maszyn m.in. o mikrostrukturyzację powierzchni w celu polepszenia właściwości tribologicznych [1]. Mikroobróbka laserowa jest jednak domeną tych obszarów wytwarzania, w których elementarnym i realizowanym w sposób ciągły celem jest miniaturyzacja.…”

Przedstawiono wybrane wyniki zastosowania lasera włóknowego w wytwarzaniu elementów mikrosystemów i biernych elementów elektroniki o submilimetrowych wymiarach z materiałów półprze-wodnikowych, ceramicznych i przewodzących. Technologie laserowe w tej skali wykorzystują ablacyjne oddziaływanie wiązki laserowej. Optymalizowanie procesów w dużej mierze było wspierane modelowaniem komputerowym. Wyniki potwierdzają możli-wość precyzyjnej mikroobróbki za pomocą lasera generującego impulsy nanosekundowe. SŁOWA KLUCZOWE: impulsy nanosekundowe, lasery włóknowe, ablacja, krzem, ceramika Selected results of the use of fiber laser for producing elements of microsystems and passive electronic elements of submillimeter dimensions in semiconductor, ceramic and conductive materials are presented. Laser technology at this scale uses ablative interaction of laser beam. Optimization of processes was significantly supported by computer modelling. The results confirm the possibility of precise micromachining using a laser with nanosecond pulses.

“…One of the main advantages of laser as a tool for material processingis the ability to precisely control where and at what rate energy is deposited. This control is carried out by appropriate selection of laser processing parameters in order to achieve the desired material modification [1,[5][6][7][8].…”

“…Surface texturing has been used for many years as a method of improving tribological properties of surfaces. The formation of a controlled texture on one of two sliding surfaces in relative motion can have many positive effects, such as reduction of friction and wear and increase in the capacity of a sliding pair [1,5].…”

AbstractLaser surface texturing is currently the most developed technique for producing fully reproducible microcavities on the surfaces of machine elements. From the point of view of texture technology, an important aspect is the proper selection of process parameters to obtain texture elements with desirable and repetitive geometries and physicochemical properties. Surface texturing improves mottling and fretting resistance and is also used wherever the adhesion properties of surface layers (printing techniques, bonding materials, biological and chemical activity, coatings, etc.) are important. The article shows the possibility of applying statistical functions to the selection of appropriate machining parameters to obtain microgeometry useful in the application of textured surfaces [1].

Laser surface texturing is used more and more often in modern machines for the implementation of variety of purposes such as for example intensification of lubrication, intensification of heat exchange, stimulation of microfluidics, increasing the chemical activity of the surface. Owing to the development of technologies using a concentrated energy flux, including laser microprocessing, it has become feasible. The present paper concentrates on the selection of parameters of laser microprocessing with picosecond pulses so as to obtain the highest efficiency and accuracy of the execution of a single texture element.Keywords: laser microprocessing, laser surface texturing (LST), laser ablation, ultrashort pulses W nowoczesnych maszynach dla realizacji różnych celów m.in. takich jak przykładowo intensyfikacja smarowana, intensyfikacja wymiany ciepła, stymulowanie mikroprzepływów, zwiększenie aktywności chemicznej powierzchni; coraz częściej stosuje się teksturowanie powierzchni. Stało się to możliwe dzięki rozwojowi technologii wykorzystujących skoncentrowany strumień energii, do których należy mikroobróbka laserowa. Tematyka opracowania koncentruje się na analizie parametrów mikroobróbki laserowej impulsami pikosekundowymi w celu osiągnięcia jak największej wydajności i dokładności wykonania pojedynczego elementu tekstury.
