20140061056 | METHODS FOR THE IMPLEMENTATION OF NANOCRYSTALLINE AND AMORPHOUS METALS AND ALLOYS AS COATINGS - Methods for the use of nanocrystalline or amorphous metals or alloys as coatings with industrial processes are provided. Three, specific, such methods have been detailed. One of the preferred embodiments provides a method for the high volume electrodeposition of many components with a nanocrystalline or amorphous metal or alloy, and the components produced thereby. Another preferred embodiment provides a method for application of a nanocrystalline or amorphous coatings in a continuous electrodeposition process and the product produced thereby. Another of the preferred embodiments of the present invention provides a method for reworking and/or rebuilding components and the components produced thereby. | 03-06-2014 |
20140242409 | ARTICLES INCORPORATING NICKEL TUNGSTEN ALLOY DEPOSITS HAVING CONTROLLED, VARYING, NANOSTRUCTURE - Bipolar wave current, is used to electrodeposit a nanocrystalline grain size. Polarity Ratio is the ratio of absolute value of time integrated amplitude of negative and positive polarity current. Grain size can be controlled in alloys of two or more components, at least one of which is a metal, and at least one of which is most electro-active, such as nickel and tungsten and molybdenum. Typically, the more electro-active material is preferentially lessened during negative current. Coatings can be layered, each having an average grain size, which can vary layer to layer and also graded through a region. Deposits can be substantially free of either cracks or voids. | 08-28-2014 |
20140255693 | Oligocrystalline Ceramic Structures for Enhanced Shape Memory and Pseudoelastic Effects - Shape memory and pseudoelastic martensitic behavior is enabled by a structure in which there is provided a crystalline ceramic material that is capable of undergoing a reversible martensitic transformation and forming martensitic domains, during such martensitic transformation, that have an average elongated domain length. The ceramic material is configured as an oligocrystalline ceramic material structure having a total structural surface area that is greater than a total grain boundary area in the oligocrystalline ceramic material structure. The oligocrystalline ceramic material structure includes an oligocrystalline ceramic structural feature which has an extent that is less than the average elongated domain length of the crystalline ceramic material. | 09-11-2014 |
