摘要： A swellable packer assembly that includes a mandrel, a sealing element disposed about a least a portion of the mandrel, and a degradable metal coating disposed about at least a portion of an outer surface of the sealing element. The degradable metal coating fluidly isolates the portion of an outer surface of the sealing element from an exterior of the coating and the sealing element is formed of a material responsive to exposure to a fluid in a wellbore to radially expand from the mandrel. The degradable metal coating is selectively removable from the mandrel downhole so as to expose the sealing element to the fluid in the wellbore.

摘要： Disclosed herein are magnesium alloys and methods of making and use thereof. For example, disclosed herein are magnesium alloys comprising: from 0 to 1.5 wt. % Zn; from 0 to 1.5 wt. % Al; less than 0.2 wt. % Ca; from 0.2 to 0.4 wt. % Ce; from 0.1 to 0.8 wt. % Mn; and the balance comprising Mg. In some examples, the magnesium alloy comprises less than 1 wt. % Zn. In some examples, the magnesium alloy comprises less than 1 wt. % Al. In some examples, the magnesium alloy exhibits substantially no incipient melting when extruded with a ram speed of from 1.00 to 10.00 ipm. In some examples, the magnesium alloy is substantially free of a Mg2Ca phase, an AlCaMg phase, an Al2Ca phase, a Ca2Mg6Zn3 phase, or a combination thereof. In some examples, the magnesium alloy is substantially free of a Mg2Ca phase.

摘要： The present invention relates to a method for preparing a dual-layer magnesium alloy with fluoride and biopolymer coatings, wherein the dual-layer MgF2/PCL coating exhibits improved corrosion resistance as compared to fluoride-coated samples or uncoated Mg samples, and has excellent cell viability, cell adhesion and cell proliferation. Accordingly, the magnesium alloy provided with the dual MgF2/PCL coating layer controls corrosion degradation of conventional orthopedic Mg alloys and exhibits excellent biocompatibility, thus being useful as an implant for fixing bones.

摘要： The present invention provides an ultrafine-grained profile of twin-crystal wrought magnesium alloys, preparation process and use of the same. In the process, raw materials of magnesium alloys are firstly smelted and cast, and are subjected to solution treatment at 300˜500° C.; then a preform is pre-deformed, so that a great amount of twin crystal microstructure forms in the magnesium alloys and the grain size of not larger than 100 μm is achieved; subsequently continuous ECAP process is performed at 200˜350° C., and the die is replaced in according to requirement so as to obtain the desired profile. The ultrafine-grained profile of magnesium alloys prepared in the invention has the grain sizes of from 100 to 450 nm, the tensile strength of 300˜400 MPa, and the elongation of 20˜35%. The length of the profile can be more than 10 m, meeting the needs of continuous production.
