Hollow composite ferrite micro-spheres were prepared by spray-drying the precursors followed by a flame-spraying.

As a new way of combustion,catalytic combustion breaks the flammable limits of conventional flame combustion,and realizes the combustion of ultra-natural gas/air mixture under the flammable limits.

Fiber Sensor and Measuring System for Studying the Influence of Combustion Flame on the Thermal Boundary in Cylinders of Diesel Engine;

The extinguishment processes of combustion flames of PMMA by 2H-heptafluoropropane and CO_2 were investigated through using a laboratory-scale combustion chamber with two parallel glass windows,and the digital photographing technology.

The measurement of the combustion flame temperature on the different positions by normal direction in cylinder of diesel engine was conducted.

WC/Ni coating was made on TC4 alloys surface by using flames spray-welding,and the microstructure, composition,phase structure and microhardness of the coating were tested and analyzed.

The possibility of Ni-based WC coating on titanium alloys substrate through flames spray-welding technique was explored,and the microstructure and properties of the coating were determined using SEM,XRD and so on.

Two kinds of Ni-base coatings with 0% and 4% La2O3 addition respectively on titanium alloys substrate made by flames spray-welding technique were prepared, and their microstructure, elemental distribution, micro-hardness and tribological properties under dry sliding against steel were studied.
