    Abstract: Methods for profiling a bore of an engine block are provided. Methods can comprise profiling the bore surface with a qualitative optical device (QlOD) to determine a qualitative surface characteristic map of the bore surface, wherein the QlOD comprises a light source configured to emit light toward the bore surface at an emitting angle, and a sensor array configured to sense scattered light reflected from the bore surface, and comparing the qualitative surface characteristic map to a calibration value to determine the suitability of the bore surface for thermal spray deposition. Methods can further include profiling the bore surface with a quantitative optical device (QnOD) to determine a quantitative surface characteristic, and determining a quantitative-qualitative correlation. Methods can further include profiling additional sample areas of the bore surface with the QlOD to determine a qualitative surface characteristic map of the bore surface and applying the correlation to the map.

    Abstract: A computer-implemented system and method of rapidly predicting at least one of residual stress and distortion of a quenched aluminum casting. Input data corresponding to at least one of topological features, geometrical features and quenching process parameters associated with the casting is operated upon by the computer that is configured as a neural network to determine output data corresponding to at least one of the residual stress and distortion based on the input data. The neural network is trained to determine the validity of at least one of the input data and output data and to retrain the network when an error threshold is exceeded. Thereby, residual stresses and distortion in the quenched aluminum castings can be predicted using the embodiments in a tiny fraction of the time required by conventional finite-element based approaches.

    Abstract: A method of activating the surface of an aluminum-based substrate. This method includes cleaning the substrate surface, and operating a plasma spraying device such that a air plasma jet produced by the device is accelerated toward the surface so that it removes or decomposes any remaining oxides and other surface contaminants. In one form, the surface being treated forms part of a cylinder bore of an internal combustion engine block. In a particular form where a protective coating is subsequently being applied to the substrate, a sequential series of plasma spraying devices may be used such that a first—preferably simpler—device is used to perform activation or pretreatment operations, while a second—and more comprehensive—device may be used to deposit the protective layer on the pretreated surface.

    Abstract: Adhesion testing of coatings to the cylinder bore of an engine block. An adhesion testing fluid is dispensed from a nozzle that simultaneously rotates so that the fluid impinges about a substantial inner periphery defined by the coated cylinder bore. The performance of a referee coated engine block is used to provide parameters for one or more production-oriented engine blocks. This allows for rapid evaluation of a sizable sample of such production-oriented engine blocks. The fluid-dispensing nozzle is configured to simultaneously provide complete circumferential coverage of the cylinder bore with high-pressure/high-velocity fluid through rotational movement of the nozzle within the bore. By keeping the production-oriented engine blocks stationary during the test further improves testing efficiency.
