Improving durability of hot forging tools by applying hybrid layers

Autor: Z. Gronostajski, M. Kaszuba, M. Hawryluk, M. Marciniak, M. Zwierzchowski, A. Mazurkiewicz, J. Smolik

Publikováno v: Metalurgija, Vol 54, Iss 4, Pp 687-690 (2015)

This paper deals with problems relating to the durability of the dies used for the hot forging of spur gears. The results of industrial tests carried out on dies with a hybrid layer (a nitrided layer (PN) + physical vapor deposition (PVD) coating) ap

Microscopic evaluation of mechanical burr degradation mechanisms after rotational atherectomy

Autor: W J Zimoch, Z Gronostajski, M Kaszuba, K Reczuch

Publikováno v: European Heart Journal. 43

Background Rotational atherectomy is a highly effective technique to facilitate percutaneous intervention on highly calcified coronary lesions. In some cases, despite numerous passages of the burr, successful crossing of the lesion is impossible. Emp

Esophageal varices during pregnancy in the course of cirrhosis

Autor: A, Stelmach, Ł, Słowik, B, Cichoń, M, Lemm, M, Poński, M, Kaszuba, I, Bakon, A, Witek

Publikováno v: European review for medical and pharmacological sciences. 24(18)

Esophageal variceal bleeding is one of the most severe complications that may occur during pregnancy in patients with liver cirrhosis. It may result in death of the mother and the fetus. Therefore, screening endoscopy should be performed both before
