Abstract
Official abstract text for this publication.
Provided is a compact thermal spray powder suitable for forming a ceramic thermal spray coating which is compact and excels in durability. The thermal spray powder disclosed herein includes ceramic particles formed of a ceramic material with a melting point equal to or lower than 2000° C. The thermal spray powder is configured such that the peak top of a main peak is in a range of 10 μm or less in a log differential pore volume distribution obtained by a mercury porosimetry, and when the peak top of a second peak is at a fine pore size less than that of the peak top of the main peak, the ratio (H2/H1) of the height H2 of the second peak to the height H1 of the main peak is 0.05 or less.
First claim
Opening claim text (preview).
What is claimed is: 1. A thermal spray powder comprising: ceramic particles formed of a ceramic material with a melting point not higher than 2000° C., a log differential pore volume distribution obtained by a mercury porosimetry for the ceramic particles having a peak top of a main peak in a range of 10 μm or less, and having a peak top of a second peak located at a fine pore size less than the peak top of the main peak, the ratio (H2/H1) of a height H2 of the second peak to a height H1 of the main peak being 0.05 or less, wherein H1 is based on gaps between the ceramic particles and H2 is based on fine pores on the ceramic particle surface. 2. The thermal spray powder according to claim 1 , wherein an average particle size of the ceramic particles is in the range from 1 μm to 20 μm inclusive. 3. The thermal spray powder according to claim 1 , wherein the ceramic material includes a halogen element.
