Properties of TiN and TiAlN Coatings Deposited onto Samples made from High Speed Steel by Sarc PVD Technique

Kottfer D., Kuffová M.

Problemy Mechatroniki : uzbrojenie, lotnictwo, inżynieria bezpieczeństwa

2013

Vol. 4, Nr 1 (11)

7-18

The paper deals with assesssment of selected properties of TiN and TiAlN coatings deposited on specimens from the high speed steel HS6-5-2-5 (STN 19 852) by Sarc PVD technique. There were essessed trobological properties such friction coefficient and wear. Wear rate was evaluated as a depth of wear. Selected mechanical properties such thickness and chemical composition of coatings, hardness and Young' modulus were assessed. These Al based coatings were tested by selected methods. Measured properties were compared to other authors.

Problemy Mechatroniki : uzbrojenie, lotnictwo, inżynieria bezpieczeństwa

2010

Vol. 1, Nr 1 (1)

11-20

The paper deals with utilization of the laser rangefinder for navigation and mapping of unknown indoor environment. The navigation algorithm is based on comparison of two pictures of the unknown space and gain of the correlation function maximum. The 2D position change of the rangefinder is calculated as a maximum of the correlation function. The goal is to improve the accuracy of odometric and inertial methods for localization and navigation of a robot system in an indoor environment.
