Wear resistence and hardness of tungsten implanted sequntially with 60 keV ions of boron and carbon (fluences Φ = 1 × 10¹⁵ - 3 × 10¹⁵ - 1 × 10¹⁶ - 3 × 10¹⁷, ion × cm^-2) at 300-350 K tempertures has been studied. For testing hardness of samples modified by Φ = 1 × 10¹⁵ - 3 × 10¹⁵ ion × cm^-2 and 1 × 10¹⁶ - 3 × 10¹⁷ fluences ion × cm^-2 nano-indentation and micro-indentation methods have been used, respectively. Determination of wear-resistance has been conducted by method of abrasive wear with dry friction. As a result, new composite materials with 1.3-4.5 times improved hardness and 2.0-6.7 times improved wear-resistance has been obtained with maintaining their rest properties. Influence of radiation processes and nano-physical phenomena on mechanical properties has been discussed.
