Abstract

An exhaust component for a motor vehicle having improved corrosion resistance includes an inner volume, an inlet for receiving exhaust gas, and an outlet for exhausting the exhaust gas. The exhaust component includes at least one wall made of diffused surface alloy sheet metal. The diffused surface alloy metal sheet includes secondary metal that is formed by diffusion into the primary metal substrate. A weld bead is applied to at least one of the edges of the diffused surface alloy metal sheet to protect the edge or to join the edge of the diffused surface alloyed metal sheet to another diffused surface alloyed metal sheet. The weld bead includes a high chromium content filler metal to protect the weld bead and primary metal base at the weld joint from corrosion.

Description

technical field [0001] The present disclosure relates generally to exhaust components for motor vehicles and more particularly to exhaust components made from diffused surface alloy sheet metal. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Motor vehicles typically have an exhaust system that conveys hot exhaust gases from the internal combustion engine that powers the motor vehicle to the outside environment. Such exhaust systems typically include various exhaust components including, but not limited to, headers, downpipes, x-pipes, tailpipes, and mufflers. Depending on the type of fuel source used to power the internal combustion engine in a motor vehicle (e.g., gasoline versus diesel), the exhaust system may include additional exhaust components that provide emission control, including, but not limited to, catalytic converters, urea Injectors...
