摘要： The present invention relates to a cuffing insert for turning in heat resistant superalloys and stainless steels comprising a very fine grained hard substrate and a coating. The substrate comprises WC from about 5 to about 8 wt % Co and from about 0.3 to about 1.5 wt % Cr. In addition to that ppm levels of Ti and Ta are present. The ratio of Me/Co=(at-% Ti+ at-% Nb+ at-% Ta)/at-% Co is lower than or equal to about 0.014−(CW_Cr)*0.008 and higher than about 0.0005. The average sintered WC-grain size is from about 0.5 to about 0.95 μm and CW_Cr from about 0.75 to about 0.95. The cemented carbide body is coated with a PVD TixAl1-xN-coating with an average composition of x being greater than about 0.4 but less than about 0.9, present as a single or multilayer coating with a total thickness of from about 1 to about 6 μm.

摘要： A medical dressing having a geometrical plane of symmetry. A border portion extends along the contour of the pad. A central portion of the dressing has a smaller width perpendicular to the plane of symmetry than the widths of the adjoining portions. The medical dressing comprises a gripping tab which is coplanar with the border portion and which projects outwardly from the border portion. The medical dressing may be used for pressure ulcer prevention, such as at a heel of a human body.

摘要： A TiC-based cermet body includes TiC and WC so that the atomic ratio Ti/W is between 2 to 5, and cobalt as the binder phase is present in an amount of between 5 to 25 vol %. Further, the cermet body has at least one element from group V of the periodic table, Mx, so that the atomic ratio Ti/Mx is between 4 to 20 and the atomic ratio W/Mx is between 1 to 6. The cermet body also has Cr in an amount such that the atomic Cr/Co ratio is from 0.025 to 0.14. The cermet body includes both undissolved TiC cores with a rim of (Ti,W,Mx)C alloy as well as (Ti,W,Mx)C grains which have been formed during sintering. A method of making a cermet body is also disclosed.
