“…[5][6][7][8] However, unexpected shortcomings (e.g., embrittlement) in such composites usually occur. In addition, so far, other methods, such as electroless coating [9,10] and flame spray processing, [11,12,13] have not been very effective. It is therefore necessary to develop novel materials or techniques to solve this issue.…”

Surface laser cladding using CO 2 laser beam irradiation was used to develop iron-based powder coatings containing nano-Al 2 O 3 particles. The microstructural and mechanical, in particular, tribological, behaviors of the developed materials were investigated by means of scanning electron microscopy (SEM), energy-dispersive spectroscopy, and X-ray diffraction as well as Vickers microhardness and friction and wear testers. It was demonstrated that mechanical properties, especially, the wear resistance of the material, can be significantly improved with the addition of the nano-Al 2 O 3 particles due to the refined grains on surfaces and the dispersion strengthening and hardening of nano-Al 2 O 3 particles. The detailed mechanism responsible for such unique wear performance was further discussed. The current study provides a potential simple and practical technique for the development of stable nanomaterials.

“…Indeed, with experimental values ∆C Na , ∆C m and C m , equation (12) represents an implicit equation, from which Φ can be easily obtained by an iterative method using as initial value Φ = 1. Afterwards, knowing C m and Φ, the real sodium concentration can be calculated by equation (1). It is interesting to evaluate the error of sodium concentration determination if the non linear dependence between C m and C Na is not taken into account.…”

“…Many composite materials like Ag-CdO, AgSnO 2 , Ag-NiO, Ag-CuO… have been used or are being developed as contact materials [1]. The mechanical, electrical and metallurgical properties of such composite materials are mainly governed by the powder processing technique as these properties lay on the homogeneity of the metal oxide phase dispersion in silver.…”

“…The mechanical, electrical and metallurgical properties of such composite materials are mainly governed by the powder processing technique as these properties lay on the homogeneity of the metal oxide phase dispersion in silver. As a result, there are several powder processing routes [1]. The present investigation starts with the precipitation of silver oxide in the presence of a metal oxide phase by mixing silver nitrate and sodium hydroxide solutions.…”

Abstract. The presence of silver ions deforms strongly the linear response for sodium determination by flame spectrophotometry. Relative errors up to 60 % can be obtained if linear instead of non-linear relations are used. A correction function is defined and a method based on mathematical considerations is proposed for elimination of interference in determination of sodium concentration.relative error if the non linear dependence between C m and C Na is not taken into account [%] q amount of sodium adsorbed on solid silver oxide [mg/kg] Φ(C Na , C Ag ) correction function Keywords.
