Overlay inspection

I have a situation where a casting has been overlayed with a wear resistant WC coating. The overlay naturally has numerous check cracks in it which is not a problem, but the piece was subsequently bent (3 pt bend), which subsequently produced some horizontal cracks and spalling in some of the pieces. I tried running UT on some of the pieces that spalling was not readily noticible and I am having a hard time conclusively determining if there are horizontal cracks (do not know if I am picking up the check cracks (some what vertical) or the horizontal cracks).
So is UT the best method for inspecting for horizontal cracks or is there another inspection process that might be better.

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
