From the aerospace to semiconductor industries, technical ceramics are gaining traction in many areas of modern manufacturing. Acoustic emission process control holds great potential for the ceramic industry, but conventional sensors face serious challenges in the field.
Marino facilitated a consensus of the testing facilities, industry discussion, and the review of data with the ASTM committee to build consensus for the balloting process to consider adopting a new process for water absorption testing and ceramic tile classification.

ASTM International Committee C21 on Ceramic Whitewares and Related Products recently recognized Ryan Marino, standards development and research manager for the Tile Council of North America (TCNA), with an Award of Appreciation for his contributions to the revision of ASTM standard C373, a transformative contribution to water absorption testing and ceramic tile classification.
Line confocal sensors, and the scanners based on them, can be used in the imaging of shiny and mirror-like surfaces, transparent materials, and multi-layered structures in various metrology and inspection applications.
In the late 2000s, researchers at Technical Research Center of Finland (VTT) invented a new optical method to image 3D microtopography of surfaces at sub-micron resolution. This method, called line confocal imaging (LCI), is based on capturing a continuous line of light reflections in visible spectrum from more than 2,000 lateral surface points simultaneously.
Measuring density is crucial for the manufacture of many of today’s products. Being able to characterize the structure and quality of solid materials quickly and efficiently can not only help guide development and manufacturing processes, it also influences the quality of the end products.
According to the company, customers now can be assured that when they purchase an AMETEK Land instrument, it is provided with a certificate of conformity confirming that the instrument has been manufactured and inspected to documented procedures, in accordance with ISO 9001:2008, and calibrated against national and international standards.

AMETEK Land recently announced that it has standardized all certificates of conformity for its fixed thermal imagers and line scanners, including the ARC, NIR, NIR-B borescope, LSP-HD line scanner, FTI-Eb borescope and FTI-E instruments.
Internal defects (usually described as cracks or voids) in the diamond inserts that make up the drill head used in drilling oil wells typically consist of some type of gap in the diamond material. The mechanical forces applied to a diamond insert are so great that these defects may cause the insert to fracture, even though it cannot be scratched by the rock layers it is drilling through.
It is thus worthwhile to identify the inserts having internal gap-type defects and remove those inserts from the assembly process. Some defects in the diamond can be seen optically, but those that do not reach the surface require a different approach to make them visible.
