摘要： A high temperature-high pressure electrode for electrochemical potential measurement has a high temperature probe comprising an oxidized zirconium alloy tube member having an electroconductive core which includes a liquid electrolyte and a porous plug held in place by an oxidized zirconium alloy tube and end plug with an axial bore extending therethrough. The electroconductive core can comprise a liquid electrolyte of soaked zirconia sand and a second porous plug. In another embodiment, the zirconia sand is replaced by a surface oxidized zirconium alloy rod with grooves which extend between ends for containment of the liquid electrolyte. This embodiment also contains a second porous plug. In a modification of the latter embodiment, there is a bore in the proximal end of the surface oxidized rod which communicates with the grooves to provide electrical continuity. A Teflon sleeve forms an annular seal between the proximal end of the oxidized rod and the oxidized tube.

摘要： Both an improved method and apparatus for determining, on an accelerated basis, the susceptibility of a nickel-based alloy to suffer stress corrosion cracking within a steam generator environment is disclosed herein. The method generally comprises the steps of subjecting a mechanically stressed specimen of the alloy to a mixture of steam and hydrogen at a temperature of between about 365.degree. C. to 435.degree. C., wherein the partial steam pressure is between about 10.4 MPa to 30.4 MPa, and the partial hydrogen pressure is between about 32 kPa to 500 kPa. The improved testing apparatus of the invention generally comprises a vessel for containing a stressed specimen and a pressurized atmosphere formed of steam and hydrogen, and an inlet cell for injecting a selected amount of hydrogen into the pressurized atmosphere of the vessel which includes a diffusion membrane which is permeable to hydrogen but impermeable to the remainder of the pressurized atmosphere. The inlet cell has a tubular housing having a wall formed from a thin layer of hydrogen permeable palladium-silver alloy. The tubular housing contains a gas permeable sponge formed by sintered particles of stainless steel to prevent the thin layer of palladium-silver alloy used in the hydrogen diffusion membrane from imploding in response to the pressure within the vessel.
摘要翻译：本文公开了一种用于在加速的基础上确定镍基合金在蒸汽发生器环境内遭受应力腐蚀开裂的敏感性的改进的方法和装置。该方法通常包括以下步骤：在约365℃至435℃的温度下使合金的机械应力样品经受蒸汽和氢气的混合物，其中部分蒸汽压力为约10.4MPa至30.4 MPa，部分氢压为约32kPa至500kPa。本发明的改进的测试装置通常包括用于容纳应力样品和由蒸汽和氢气形成的加压气氛的容器，以及用于将选定量的氢气注入到容器的加压气氛中的入口单元，该容器包括扩散膜，对氢气是可渗透的，但对其余的加压气氛是不可渗透的。入口单元具有管状壳体，其具有由可透氢钯 - 银合金薄层形成的壁。管状壳体包含由不锈钢烧结颗粒形成的透气海绵，以防止氢扩散膜中使用的钯 - 银合金薄层响应于容器内的压力而侵入。
