本发明公开了一种活性元素Re改性β‑(Ni,Pt)‑Al涂层及其制备工艺，属于高温防护涂层技术领域。通过两次电镀加电弧离子镀的工艺，在Ni基单晶高温合金上制备Re改性β‑(Ni,Pt)‑Al涂层。包括以下步骤：在基体上电镀沉积Pt层；对电镀Pt层进行真空退火处理；电镀Ni‑Re层；在获得的Ni‑Re层上使用电弧离子镀沉积Al层；对获得的Al层在真空退火炉中退火获得Re改性β‑(Ni,Pt)‑Al涂层。本发明的优点：制备工艺简单，成本低；采用两次电镀的方法分别将Pt元素和Re元素加入到涂层中；涂层中的Re、Pt和Al元素含量以及涂层的厚度可精确的控制。The invention discloses an active element Re-modified β-(Ni,Pt)-Al coating and a preparation process thereof, belonging to the technical field of high-temperature protective coatings. Re-modified β‑(Ni,Pt)‑Al coatings were prepared on Ni-based single crystal superalloys by two electroplating and arc ion plating processes. The method comprises the following steps: electroplating a Pt layer on a substrate; performing vacuum annealing treatment on the electroplating Pt layer; electroplating a Ni-Re layer; depositing an Al layer on the obtained Ni-Re layer by using arc ion plating; Re-modified β-(Ni,Pt)-Al coatings were obtained by annealing in an annealing furnace. The advantages of the invention are as follows: the preparation process is simple and the cost is low; the Pt element and the Re element are respectively added into the coating by two electroplating methods; the content of the Re, Pt and Al elements in the coating and the thickness of the coating can be accurately determined control., The invention discloses an active element Re modified beta- (Ni, Pt) -Al coating and a preparation process thereof, belonging to the technical field of high-temperature protective coatings., The invention discloses a traditional Chinese medicine for treating a cerebrovascular disease. The traditional Chinese medicine is characterized by being prepared from the following raw materials in parts by weight: 0.7-1.2 parts of ginseng, 0.4-0.6 part of leech, 2.5-3.5 parts of radix curcumae, 1.5-2.5 parts of rhizoma acori graminei, 2.5-3.5 parts of cassia twig, 0.1-0.3 part of scorpion .
Abstract: The rare earth oxide ceramic designed as 4.5wt.%Gd 2 O 3-5.5wt.%Yb 2 O 3-10.5wt.%Y 2 O 3-79.5wt.%ZrO 2 (GdYbYSZ) is a candidate material for thermal barrier coatings (TBCs), which will be suitable for application at higher temperatures., Abstract: The four LZ, LZ3Y, LZ7C3 and YSZ thermal barrier coatings (TBCs)were fabricated via electron beam physical vapor deposition (EB-PVD). The high temperature phase stability, interficial bonding strength and cyclic oxidation behavior of three types of rare earth zirconates and YSZ TBCs were investigated., Abstract: Three kinds of aluminide coatings were fabricated by chemical vapor deposition（CVD）on the surface of the nickel-based superalloy substrates at the deposition pressure of 150, 200 and 250 mbar, respectively., Aviation Key Laboratory of Science and Technology on Advanced Corrosion and Protection for Aviation Material, AECC Beijing Institute of Aeronautical Materials, Beijing 100095, China, Aviation Key Laboratory of Science and Technology on Advanced Corrosion and Protection for Aviation Material, AECC Beijing Institute of Aeronautical Materials, Beijing 100095, China, .
