Gas Bearing

Ceramic materials, or more particularly aluminum oxides, have found application as a practical gas-bearing material because of the dimensional stability, low coefficient of friction, high hardness, and ability to attain good surface finish that these materials possess. This paper reports on an investigation of a number of methods designed to improve the resistance of aluminum oxide to damage from sliding contact, and hence improve the start-stop life characteristics of gas-bearing assemblies. These methods include heat-treatment, neutron irradiation treatment, gold plating, and coating of alumina surfaces by means of a chemical vapor deposition technique, in order to increase the wear resistance of the material. A brief mention is also made of the effect of machining techniques as they relate to the finish, and hence to the wear resistance, of gas-bearing parts.

Metal Working

The main reason for using ceramic materials for metal working tools is the significantly higher wear resistance with respect to commonly used steel tools and therefore the possibility to improve the lifetime as well as the product quality. Ceramic rolls were developed and tested in different applications. In this paper the work on the development of the ceramic rolls and the evaluation of several roll types in field tests are summarized.

Optimum Model

An optimum model for the composition design of the advanced ceramic material is built based on the wear resistance with the combination of both theoretical and experimental methods, with KIC 3/4×H1/2 working as the coefficient of wear resistance when the abrasive wear dominates. Results show that the tested SiC/(W,Ti)C/Al2O3 ceramic material can be expected to achieve the highest wear resistance when the volume fraction of SiC and (W,Ti)C is about 15% and 17%, respectively. The optimum composite is then fabricated with the hot pressing technique. Its wear resistance is approximately 43% higher than that of the pure alumina ceramic when used as the tool material in the machining of the hardened tool steel. The increment of the wear resistance of the developed ceramic material coincides well with that predicted from the optimum model. It proves that the method proposed in the present study is feasible for the ceramic materials mainly with wear mechanisms of abrasive wear.

Coating Properties

Presented in this article are the properties of flame sprayed ceramic coatings using oxide ceramic materials consisting of a powdered zirconium oxide (ZrO2) matrix with 30% calcium oxide (CaO) applied to unalloyed S235JR grade structural steel. A primer consisting of a metallic Ni-Al-Mo based powder has been applied to plates with dimensions of 5x200x300 mm and front surfaces of ø 40x50 mm cylinders. Flame spraying of primer coating was conducted using a RotoTec 80 torch, and an external surface was coated with a CastoDyn DS 8000 torch. Evaluation of the coating properties was conducted using metallographic testing, phase composition research, measurement of microhardness, abrasive wear resistance (acc. to ASTM G65 standard) and erosion wear resistance (acc. to ASTM G76-95 standard).
