The development of wear-resistant surfaces supports sustainable and long-term work of friction couples. In this paper, we demonstrated laser structuring as a method for increasing Grade-2 titanium surface wear resistance. Surface treatment by a nanosecond fiber laser produces nanoand microstructures simultaneously, with composition changing to combinations of Ti, O and N. Tribological tests were conducted according to certificated 'Ball-disk' method in conditions of rubbing friction and Al 2 O 3 -ball as a counterbody. Investigation results demonstrate an increase in wear resistance of laser-treated titanium surface by ten times. It appears both surface structure and chemical composition influence titanium durability enhancement.
The engineering management process and automation method for making pilot set of optical polymer parts used in LED systems are considered. Optical system and lens geometry development are realized in Zemax. 3D model and molding tools with further generating of NC coded data are developed in Cimatron E. Pre simulation of injection molding process is realized in Moldex 3D and thermo-mechanical analysis is provided by OOFELIE. 3D printer Objet is used for parts prototyping on different stages of the process. Data and process management are realized with a help of PDM system SmarTeam.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
