Patent number: 11919091Abstract: A coating for carbide substrates employs a nanostructured coating in conjunction with a non-nanostructured coating. The nanostructured coating is produced by the addition of a refining agent flow, particular hydrogen chloride gas, during deposition, and may be produced as multiple individual titanium and titanium-based nanostructured layers varying functional materials in a series. The combination of a nanostructured coating and non-nanostructured coating is believed to produce a cutting tool insert that exhibits longer life. Pre-treating the substrate with a mixture of compressed air and abrasive medium prior to coating the substrate and post-treating the coated substrate with a mixture of water and abrasive medium after the coating process is believed to further enhance the wear resistance and usage life of the cutting tool.Type: GrantFiled: April 15, 2020Date of Patent: March 5, 2024Assignee: P & S Global Holdings LLCInventor: Wenping Jiang

Patent number: 10752997Abstract: Ultrasonic spray deposition (USD) used to deposit a base layer on the substrate, followed by chemical vapor infiltration (CVI) to introduce a binder phase that creates a composite coating with good adherence of the binder to the initial phase particles and adherence of the composite coating to the substrate, is disclosed. We have used this process to create coatings consisting of cubic boron nitride (cBN), deposited using USD, and titanium nitride (TiN) applied using CVI in various embodiments. This process can be used with many materials not usable with other processes, including nitrides, carbides, carbonitrides, borides, oxides, sulphides and silicides. In addition, other binding or post-deposition treatment processes can be applied as alternatives to CVI, depending on the substrate, the coating materials, and the application requirements of the coating. Coatings can be applied to a variety of substrates including those with complex geometries.Type: GrantFiled: October 18, 2007Date of Patent: August 25, 2020Assignee: P&S Global Holdings LLCInventors: Wenping Jiang, Justin B.

Patent number: 10639768Abstract: A physical configuration of multiple-layer coatings formed with at least one layer of coating containing cubic born nitride (cBN) particles with one or more layers in composite form containing cBN particles may have a thickness of each individual layer as thin as in the nanometer range, or as thick as in the range of a few microns and even up to tens of microns. The chemistry of the composite layer consists of any individual phase of (a) nitrides such as titanium nitride (TiN), titanium carbonitride (TiCN), and hafnium nitride (HfN); (b) carbides such as titanium carbide (TiC); and (c) oxides such as aluminum oxide (AI2O3) or any combination of the above phases, in addition to cBN particles. The coating or film can be stand-alone or on a substrate.Type: GrantFiled: May 29, 2012Date of Patent: May 5, 2020Assignee: P&S Global Holdings LLCInventors: Wenping Jiang, Ajay P. Malshe

Patent number: 10155325Abstract: Open-architecture constituents, such as wood fibers, are coated with an intercalated functional material and bound together to form a solid product, such as a plank. Applications for this material include decking, fencing, and the like. The functional material is applied prior to forming the solid product, either as a coating on each fiber or inserted in a fiber or fiber cluster. As the constituents, such as fibers, wear during use of the product, the functional material is released to provide continual protection of the product, such as UV resistance and fungal resistance.Type: GrantFiled: December 23, 2013Date of Patent: December 18, 2018Assignee: NanoMech, Inc.Inventors: Parash Kalita, Wenping Jiang

Patent number: 9821435Abstract: A method for forming a stand-alone wafer or a coating on a substrate uses a composite of cubic boron nitride (cBN) particles and other materials, such as nitrides, carbides, carbonitrides, borides, oxides, and metallic phase materials. The wafer or coating may be formed of a thickness up to about 1000 microns for improved wear life. The density of material within the wafer or coating may be varied according to desired parameters, and a gradient of particle sizes for the cBN may be presented across the thickness of the material.Type: GrantFiled: May 29, 2012Date of Patent: November 21, 2017Assignee: NanoMech, Inc.Inventors: Wenping Jiang, Ajay P.

Patent number: 9682170Abstract: A high-strength coating for dental and orthopedic implants utilizing hydroxyapatite (HAp) nanoparticles provides for a high level of osseointegration through a range of surface pore sizes in the micro- to nanoscale. Zinc oxide (ZnO) nanoparticles may be incorporated with the HAp nanoparticles to form a composite coating material, with ZnO providing infection resistance due to its inherent antimicrobial properties. A textured surface, consisting of “islands” of roughly square coating structures measuring about 250 ?m on a side, with spacing of 50-100 ?m therebetween, may further promote the osseointegration and antimicrobial properties of the implant coating.Type: GrantFiled: August 20, 2010Date of Patent: June 20, 2017Assignees: The Board of Trustees of the University of Arkansas, NanoMech, Inc.Inventors: Ajay P.

Patent number: 9662712Abstract: An adherent coating for carbide and ceramic substrates employs a thin layer between the substrate and a subsequent layer or layers. The thin layer may be employed without thermal cracking due to heat during use, such as for the insert of a cutting tool, because the upper layer or layers provide a gradual transition of material properties to a harder, less thermally conductive material on the outermost layer. A particular arrangement of layers on the carbide or ceramic substrate may be, from innermost to outermost layer, hafnium nitride, titanium carbide, aluminum oxide, and titanium nitride.Type: GrantFiled: March 18, 2013Date of Patent: May 30, 2017Assignee: NanoMech, Inc.Inventors: Wenping Jiang, Mike Kimmel, Ajay P.

Patent number: 9649746Abstract: A cutting tool formed by a coating layer on a substrate has cutting edges that feature serrations. The linear dimensions of the serrations may vary from a few nanometers up to 10 microns. The serrations result in a smoother cut edge on the workpiece, particularly when the workpiece is formed of certain materials that are seen as particularly difficult to cut, such as hardened steels.Type: GrantFiled: May 29, 2012Date of Patent: May 16, 2017Assignee: NanoMech, Inc.Inventors: Ajay P.
