Enhancement the Wear Resistance of Parts and Tillage Tools in Agricultural Machinery by Laser Cladding DOI: 10.22184/1993-7296.FRos.2021.15.2.132.142
The paper presents the results of metallographic and tribological studies of coatings with the addition of ultrafine titanium carbide powder to the multicomponent charge. With the help of a full factorial experiment, the geometric parameters of the cladded coating were determined depending on the power, processing speed and the diameter of the laser beam. Regularities of the change in the friction coefficients on pressure and sliding speed have been obtained. Scuff resistance and wear resistance of coatings is higher than hardened steels.
IX Congress of the Russian Technology Platform PHOTONICS: the conference Laser Industrial Technologies DOI: 10.22184/1993-7296.FRos.2021.15.2.122.129
A brief overview of the scientific and technical conference “Laser Industrial Technologies” is presented. It took place in the framework of the IX Congress of the Technology platform of the Russian Federation “PHOTONICS”. The Congress accompanied the 15th Anniversary International Specialized Exhibition of Laser, Optical and Optoelectronic Technology “Photonics. World of Lasers and Optics-2021”. The development of laser industrial technologies is carried out in an integrated manner: it is in the processes of updating the regulatory framework, creating improved equipment, writing software and mathematical models of physical and chemical processes, mastering technologies and obtaining new materials.
Dependence of the Output Laser Radiation on Geometry of the Optical Fiber DOI: 10.22184/1993-7296.FRos.2021.15.2.144.150
This research is devoted to characterizing the profile of a beam emerging from a double-clad optical fiber and having different cross-sectional geometries. The influence of the first fiber cladding geometry on the mode mixing function was investigated. The efficiency of the clad-core mode transfering is determined.
