Publication number: 20240167166Abstract: Disclosed herein is a method for coating carbide substrates using nanostructured and a non-nanostructured layers. The coatings can be produced by the addition of a refining agent flow, particular hydrogen chloride gas, during deposition, and can be produced as multiple individual titanium and titanium-based nanostructured layers varying functional materials. The combination of a nanostructured layers and non-nanostructured layers can produce a cutting tool insert that exhibits longer usage life. In addition, pre-treating the substrate with a mixture of compressed air and and abrasive medium prior to coating the substrate and post-treating the coated substrate with a mixture of water and an abrasive can further enhance the wear resistance and life of the cutting tool.Type: ApplicationFiled: February 1, 2024Publication date: May 23, 2024Applicant: P&S Global Holdings LLCInventor: Wenping Jiang

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
