Structural features of Ni-Cr-Si-B materials obtained by different technologies

This study considers the structural features of Ni-Cr-Si-B (Ni - base; 15.1 % Cr; 2 % Si; 2 % B; 0.4 % C) materials obtained by different methods. The self-fluxing coatings were deposited by plasma spraying on the tubes from low carbon steel. Bulk cylinder specimens of 20 mm diameter and 15 mm height were obtained by spark plasma sintering (SPS). The structure and phase composition of these materials were investigated by optical microscopy (OM), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffractometry (XRD). The major phases of coatings and sintered materials are [gamma]-Ni, Ni[3]B, CrB and Cr[7]C[3]. We demonstrate that the particle unmelted in the process of plasma spraying or SPS consist of [gamma]-Ni-NEB eutectic and also CrB and Cr[7]C[3] inclusions. The prolonged exposure of powder to high temperatures as well as slow cooling rates by SPS provide for the growth of the structural components as compared to those of plasma coatings materials. High cooling rates at the plasma spraying by melted particles contribute to the formation of supersaturated solid solution of Cr, Si and Fe in [gamma]-Ni. The structure of the melted particles in sintering material has gradient composition: the core constituted of Ni grains of 10 μm with [gamma]-Ni-Ni[3]B eutectic on the edges. The results of the experiment demonstrate that the sintering material has a smaller microhardness in comparison with plasma coatings (650 and 850 MPa, respectively), but at the same time the material has higher density (porosity less than 1 %) than plasma coatings (porosity about 2.. .3 %)

Investigation of the structure and microhardness of Mo-Fe-C coatings obtained by the electron beam injected in the atmosphere

In this work 'Mo-Fe-C' coatings fabricated on medium carbon steel by non-vacuum electron beam cladding were investigated. The structure of coatings and transition zones were studied by scanning electron microscopy (SEM). It was shown that an increase of Fe percentage in the cladding mixture led to a decrease of the eutectic volume fraction in the coating and was accompanied by the formation of the gradient structure between the coating and a substrate material. Measurements of microhardness in the cross section of samples revealed that the cladding of a 'Mo-C powder mixture contributed to a 4.5-fold increase of microhardness

EFFECT OF FERROTHERAPY ON COURSE OF ISCHEMIC HEART DISEASE ASSOCIATED WITH MILD IRON DEFICIENCY IN MEN

Aim. To assess effect of ferrotherapy on course of ischemic heart disease (IHD) associated with mild iron deficiency anemia (IDA) and latent iron deficiency (ID). Material and methods. 80 male patients, coal miners, aged 51±7.9 years, were observed. 28 patients had angina pectoris associated with the mild IDA, 23 patients experienced myocardial infarction accompanied by the mild IDA and 29 patients had angina with latent ID. Latent ID was defined in case of iron plasma level ≤12 µg/l, IDA was diagnosed in case of hemoglobin level <130 mg/l. The minimal hemoglobin level observed in patients was 107g/l. ICD clinical characteristics were compared before and after 3-week iron-based treatment in individualized doses. Results. Latent ID and mild IDA aggravated angina and increased ectopic myocardial activity in patients with IHD. Iron-based therapy with appropriate nutrition reduced angina attacks frequency, duration and intensity, decreased nitroglycerin consumption and increased exercise tolerance. Conclusion. Normalization of haemoglobin level and iron plasma concentration in the mild IDA as well as normalization of iron plasma concentration in ID in patients with IHD reduces ede-ma and dyspnea, decreases heart rate. These effects are provided due to the treatment with elementary iron in individualized course dose, which improves clinical status and minimizes the adverse reactions
