    Abstract: A spigot assembly for connecting a coolant flow conduit to a rechargeable battery thermal management system includes a male spigot, a coolant spigot having a connector body defining an internal coolant flow cavity and having a conduit connection end opening and a male spigot connection end opening. The spigot assembly includes a ceramifiable silicone rubber seal. The connector body is configured to receive the male spigot within the internal coolant flow cavity at the male spigot connection end opening, with the ceramifiable silicone rubber seal disposed between and sealing against an outer side of the male spigot and an inner side of the connector body. A spigot assembly is disclosed that has a collar surrounding the connector body. The collar has an angled inner wall configured to align the male spigot with the connector body and shield the seal from heat. A vehicle having the spigot assembly is disclosed.

    Abstract: An exemplary method of depositing a layer of a material on an interior substrate surface of a complex geometry component includes the steps of providing the complex geometry component having an aperture defining an edge of the interior substrate surface of the complex geometry component, at least a portion of the interior substrate surface defining a first area not visible from the aperture, providing a heating element adjacent to the first area of the complex geometry component, energizing the heating element to raise a surface temperature of the first area and establish a thermal gradient between the first area and an adjacent area, and providing a vapor deposition apparatus configured to deposit the layer of material on the interior substrate surface corresponding to the first area of the complex geometry component.

    Abstract: An integrated power electronics component configured for mitigating noise, vibration, and harshness includes a case formed from metal and configured to dampen a sound wave having a first frequency and a first amplitude and propagatable in a first direction. The case has a first surface and a second surface spaced apart from the first surface, a first stiffness, and a first strength, and the first and second surfaces include a structure defining a plurality of recessions therein. The component includes a cured polymer formed from a composition disposed on at least one of the first and second surfaces in each of the recessions to thereby dampen the sound wave in the first direction and in a second direction that is perpendicular to the first direction to a second frequency that is less than the first frequency and a second amplitude that is less than the first amplitude.

    Abstract: A method of coating an inner surface of an engine cylinder bore includes cleaning the surface to remove carbon, resulting in the surface having a maximum of 30 atomic percent carbon, texturing the surface to achieve a developed interfacial area ratio of at least 100%, and heating the surface to between 100-200 degrees Celsius. A thermal spray coating is then adhered to the surface. In some cases, a force of 25+ Newtons scratched across the thermal spray coating is required to remove the thermal spray coating from the surface. Maximum adhesion strength is achieved when the coating is applied to: 1) a heated surface that has 2) an Sdr of at least 100% and 3) a maximum of 20 atomic percent of carbon on the surface. When these three criteria are all present, adhesion strength can be 50 Newtons or more with evidence of metallurgical diffusion/bonding at the interface.
