Zirconia Ceramic Automobile valves provides better performance for the automotive industry, exhibit an attractive
combination of advantageous properties, e. g. low density, good temperature and corrosion resistance. Therefore,
they have a high potential for application in combustion engines. Valves made out of sintered Zirconia Ceramic are
of primary interest. A simple substitution of metallic valves is planned as a first step. The ceramic valves promise fuel
savings and a reduction of noise emission. For a widespread use of such valves, mass production and quality control
have to be mastered reliably. Here, nondestructive testing (NDT) can yield a significant contribution. In this article, a
survey on application of various NDT techniques for testing volume and surface of valves is given. The work is based
on public and automotive industry funded research projects and on round-robin tests performed within the German
The products are made of high purity zirconia ceramic and alumina ceramic material, which have
advanced and excellent performances, fabulously popular.
