In this project, is presented a watercolor inspired method for the rendering of surfaces. This approach mimics the watercolor process by building up an illuminated scene through the composting of several layers of semi-transparent paint. The key steps consist of creating textures for each layer using Perlin Noise, and then calculating the layer thickness distribution using an inverted subtracti...

The measurement of the thicknesses of layers is important for the quality assurance of industrial coating systems. Current measurement techniques only provide a limited amount of information. Here, we show that spectral domain Line Field (LF) Optical Coherence Tomography (OCT) is able to return to the user a cross sectional B-Scan image in a single shot with no mechanical moving parts. To relia...

The release of nanomaterials from products and applications that are used by industry and consumers has only been studied to a very limited extent. The amount and the characteristics of the released particles determine the potential environmental exposure. In this work we investigated the release of Ti from paints containing pigment-TiO2 and nano-TiO2. Panels covered with paint with and without...

Abstract A salt spray test was used to evaluate the corrosion resistance of pickling high-strength steel JSH440W phosphating film on its surface, and scanning electron microscope (SEM) energy dispersive spectrometer (EDS) were analyze micro-morphology element content surface defects area sample after test. The results show that enrichment Si, Mn, O elements badly influences film-forming perform...

Abstract With the development of paints, high‐friction organic zinc‐rich paints with slip coefficients more than 0.45 have been advanced, making it possible to obtain sophisticated and higher quality high strength bolted friction joints. Moreover, comparing inorganic used at present, are appropriate for using in situ construction. However, since application conditions coatings not specified, is...

We have experimentally quantified exposure to dichloromethane during non-professional paint stripping and validated the mathematical paint exposure model of van Veen et al. (1999). The model innovates the prediction of the dichloromethane evaporation rate and room concentration by accounting for transport in the paint stripper matrix. The experiments show that peak concentrations range from 600...

A study was undertaken to determine if laser-induced breakdown spectroscopy (LIBS) can be a practical and competitive alternative to X-ray fluorescence (XRF) methods for lead-in-paint inspection. Experiments in the laboratory confirmed that LIBS is suitable for detecting lead in paint at the hazard levels defined by federal agencies. Although we compared speed, function and cost, fundamental di...

Recent developments in computer graphics software and hardware have made it possible to write computer graphics programs that can be used to solve automotive paint engineering problems. New surface reflection models have been created for simulating the appearance of automotive paint, and the hardware available today on graphics cards allows these reflection models to be evaluated in real-time. ...
