An apparatus and a method monitor fluid loss from one or more casks during a maturation process. The apparatus comprises a multi-pass absorption cell arranged in fluid communication with one or more fluid conduits, a pump and a monitoring system. The pump and fluid conduits transport a fluid sample (e.g. vapor sample) from a perimeter of the one or more casks to the multi-pass absorption cell. The monitoring system detects and identifies fluid within the multi-pass absorption cell.

Maturation monitoring apparatus and methods

A layer system and a method for producing a component having such a layer system are provided. The layer system includes a substrate a substrate, at least one MCrX layer on the substrate, and a chromium-rich layer on or in the at least one MCrX layer. X includes at least one element selected from the group consisting of yttrium (Y), silicon (Si), aluminum (Al) and boron (B). M includes at least one element selected from the group consisting of nickel (Ni) and cobalt (Co).

Layered coating system with a MCrAlX layer and a chromium rich layer and a method to produce it

A method of forming a gas turbine part includes forming a bonding underlayer on a superalloy metal substrate, the underlayer including an intermetallic compound of aluminum, nickel, and platinum, and forming a ceramic outer layer on the alumina film formed on the bonding underlayer. The bonding underlayer essentially comprises an Ni&#x2014;Pt&#x2014;Al ternary system constituted by an aluminum-enriched &#x3b1;-NiPt type structure, in particular an Ni&#x2014;Pt&#x2014;Al ternary system having a composition NiPtAlin which,, andare such that 0.05&#x2266;z&#x2266;0.40, 0.30&#x2266;y&#x2266;0.06, and 0.15&#x2266;x&#x2266;0.40.

Method of forming a thermal protective coating on a super alloy metal substrate

A gas turbine part comprises a superalloy metal substrate, a bonding underlayer formed on the substrate and comprising an intermetallic compound of aluminum, nickel, and platinum, and a ceramic outer layer anchored on the alumina film formed on the bonding underlayer. The bonding underlayer essentially comprises an Ni&#x2014;Pt&#x2014;Al ternary system constituted by an aluminum-enriched &#x3b1;-NiPt type structure, in particular an Ni&#x2014;Pt&#x2014;Al ternary system having a composition NiPtAlin which z, y, and x are such that 0.05&#x2266;z&#x2266;0.40, 0.30&#x2266;y&#x2266;0.60, and 0.15&#x2266;x&#x2266;0.40.

Gas turbine part provided with a protective coating

A protective coating forming a thermal barrier is made on a superalloy metal substrate by forming a bonding underlayer on the substrate, the bonding underlayer being constituted by an intermetallic compound comprising at least aluminum and a metal from the platinum group, and by forming a ceramic outer layer which is anchored on a film of alumina present on the surface of the bonding underlayer. The bonding underlayer preferably has a thickness of less than 50 &#x3bc;m and is made by using physical vapor deposition, e.g. by cathode sputtering, to deposit a plurality of individual layers alternately of aluminum and of a metal from the platinum group, and by causing the metals in the resulting layers to react together exothermally.
