    摘要: A method of estimating the lifetime of a thermal barrier coating (14), which is applied to the surface of a member subjected to cyclical thermal loads, especially a vane and/or blade of a gas turbine, by means of a bond coat (12) lying in between the coating and the member, leads to more accurate results with simplified calculation by determining, in a first step, the amplitude of the normal stress (&Dgr;&sgr;n) perpendicular to the interface between the bond coat (12) and the thermal barrier coating (14) during cyclical loading, and calculating, in a second step, the number Ni of cycles to failure for every normal stress amplitude (&Dgr;&sgr;n) in accordance with the formula N i ⁢   = C ⁡ ( △σ n σ 0 ) m where &sgr;0 is a stress reference value and C(&dgr;ox) and m(&dgr;ox) are material parameters, which depend on the thickness (&Dgr;ox) of an oxide layer (13), which is located between the thermal barrier layer (14) and the bond coat (12) and grows with the cyclical loading.

    摘要: Elemental fluorine is often manufactured electrochemically from a solution of KF in hydrogen fluoride and contains varying amounts of entrained electrolyte salt in solid form as impurity. The invention concerns a process for the purification of such impure elemental fluorine by contact with liquid hydrogen fluoride, e.g., in a jet gas scrubber or by bubbling the raw fluorine through liquid hydrogen fluoride. After this purification step, any entrained hydrogen fluoride is removed by adsorption, condensing it out or both. After passing through a filter with very small pores, the purified fluorine is especially suited for the semiconductor industry as etching gas or as chamber cleaning gas in the manufacture of semiconductors, TFTs and solar cells, or for the manufacture of micro-electromechanical systems (“MEMS”).

    摘要: An electrolyzer apparatus for the electrolytic manufacture of elemental F2 from an electrolyte/HF-solution, e.g., KF×1.8 HF, comprising at least one electrolytic cell which contains at least two anodes, often 20 to 30 anodes, a metallic cathodic vessel, and at least two rectifiers such that each anode is allocated to one rectifier. In this manner, each anode can be controlled and regulated individually. Failure of each individual anode, e.g., anode break, causes the production of undesired side products, e.g., of CF4. Any faulty anode can be detected easily, and each anode can be shut off individually, if needed, and repaired.
