Stress in Diamond

High stresses and/or degraded adhesion during machining result in coating failure and the exposed substrate suffers from massive deformation and rapid wear. Table 1: Characteristics of diamond tools Recently a microwave-plasma CVD technology has been developed to increase the diamond growth rate and, with nitrogen gas, to produce fine diamond grains on the order of 10 nm (Catledge and Vohra

Organic silicon for medical devices

Silicon dioxide, or silica, is one of the most fundamental elements on earth. Most commonly found in nature as quartz, it is the major constituent of sand and a primary component in silicone and glass. Now, this basic chemical compound is being applied using plasma-enhanced chemical vapor deposition (PECVD) techniques as an anti-microbial barrier, a primer to promote adhesion between stainless

Tungsten Disulfide (WS2) Low Friction Coating per

Tungsten Disulfide (WS2) is a low friction dry lubricant coating that improves performance and service life better than other dry lubricants by reducing friction noise, improving mold release, and solving problems of excessive wear, seizing, galling and fretting.

Organic silicons' role in surface modification of medical

Organic silicon PECVD The PECVD process deposits thin films from a gas state (vapor) to a solid state on a substrate. PECVD deposition of silicon dioxide often requires organic silicons are as the feedstock. Within this family, the best known are

Fixing Problems with Vacuum Metallizer

Troubleshooting coating defects on batch vacuum metallized parts can be frustrating and time-consuming. Productivity declines and costs rise as time is spent chasing problems. A systematic approach which identifies metallizing problems and proposes solutions can reduce the

How to Remove Parylene Coating

Properly preparing the substrate prior to coating yields better adhesion; preparation includes both cleaning the substrate and, if necessary, employing an adhesion promoter such as A-174 silane. In addition to making sure that the parylene coating is applied where required, it is equally as important to prevent no-coating zones from being coated.

US Patent for Systems and methods for multi

Systems and methods are provided for sample processing. A device may be provided, capable of receiving the sample, and performing one or more of a sample preparation, sample assay, and detection step. The device may be capable of performing multiple assays.

NADCAP Specifications for Conformal Coatings

Prior to Nadcap's creation, aerospace, defense and related firms verified process-compliance through audits of their own suppliers. Often extreme similarity resulted from their own process analyses for verifying compliance, because these processes paralleled those provided by the suppliers.

Refractory Metal Coatings Freestanding Structures

Through chemical vapor deposition, Ultramet fabricates refractory metal coatings and freestanding structures of tungsten, rhenium, tantalum, molybdenum, and niobium. Complex geometries are produced on removable mandrels, and the rapid deposition rate allows manufacture of

US Patent for Aluminide coating process Patent (Patent #

It is believed that all prior attempts to rearrange the manufacturing sequence so that cooling hole machining and internal aluminide coating are performed after TBC deposition have failed because of the incompatibility of the halide activator and TBC materials.

Dry machining of aluminum–silicon alloy using polished

2006/3/15Prior work showed that CVD tools can have a life of more than 3.5 min when machining this alloy using lab-deposited and polished inserts. But in this study, both polished and unpolished inserts failed prematurely by 'massive delamination' of the coating.

NASA Evaluation of ESD Effects

Depending upon the type of coating material and product requirements, conformal coating may be applied by dipping, brushing, spraying, dispensing or chemical vapor deposition. In order to rework or repair parts on PWAs, the conformal coating must be removed, either entirely or in specific areas.

Silicon carbide optics for high energy applications

Joe Salemi and Mike Albrecht look at the manufacture of silicon carbide (SiC) optics Silicon Carbide (SiC) optics are becoming more and more prevalent in High Energy Laser (HEL) designs, so it is important that manufacturers are aware of the potential risks when using these materials early in the product development process, thereby avoiding what could be costly and time-consuming problems if

SilcoTek Coating Process

That's why creating a pristine, contaminant free surface prior to coating is critical for optimal results and good visual appearance. Unfortunately metal working and machining processes can impart contamination throughout the part surface that is hidden to the naked eye, so be sure to help us understand everything your parts have been exposed to prior to sending them to us for coating.

Custom Tooling Unmasks Process Costs in Metal

The company has a physical vapor deposition (PVD) process involving metal vapor applied within a vacuum that adds a 1-micron-thick metal coating to all part surfaces not blocked by masking. Yet because some surfaces of almost any part must be kept free of the coating for the sake of assembly, applying or attaching masking to every piece is generally a major labor component of PMT's work.
