摘要： A chemical vapor deposition apparatus includes: a reaction chamber in which deposition materials are housed a gas supply tube provided in the reaction chamber and a rotary drive device that rotates the gas supply tube about a rotation axis. A an inside of the gas supply tube is divided into a first gas flowing section and a second gas flowing section both of which extend along the rotation axis. A first gas ejection port ejects a first gas flowing in the first gas flowing section into the reaction chamber, and a second gas ejection port ejects a second gas flowing in the second gas flowing section into the reaction chamber. The first port and the second port form an ejection port pair in a plane perpendicular to the rotation axis.

摘要： In a surface-coated cutting tool, a hard coating layer composed of a lower layer and an upper layer is deposited on a surface of a tool body made of a WC-based cemented carbide or a TiCN-based cermet. The lower layer has at least one Ti compound layer made of a TiCN layer and the upper layer is made of an α-type Al2O3 layer. In a case where, regarding Al2O3 crystal grains of the entire upper layer, a constituent atom-sharing lattice point distribution is measured, a highest peak is present in Σ3, and a distribution ratio of Σ3 is 70% or more. A ratio of a Σ3-coincidence grain boundary continuing from an interface between the lower layer and the upper layer to an outermost surface of the upper layer is 60% or more of a Σ3-coincidence grain boundary of the upper layer.

摘要： A surface-coated cutting tool includes a tool body made of a tungsten carbide-based cemented carbide or a titanium carbonitride-based cermet and a hard coating layer that includes a lower layer and an upper layer and formed on the tool body. The lower layer is composed of a Ti compound layer including at least a TiCN layer. The upper layer includes an Al2O3 layer having an α-type crystal structure. In the Al2O3 crystal grains of the upper layer, when a coincidence grain boundary distribution graph is measured, sulfur is segregated in a grain boundary of Σ31 or more and a grain boundary length thereof is 20% to 50% relative to the whole grain boundary length in the constituent atom sharing lattice point form of Σ3 or more. Absolute values of residual stress of a flank face and a rake face are 100 MPa or less.

摘要： The hard coating layer of the cutting tool includes a complex nitride or complex carbonitride layer expressed by the composition formula: (Ti1-xAlx)(CyN1-y). xavg and yavg satisfy 0.60≤xavg≤0.95 and 0≤yavg≤0.005. xavg is an average content ratio of Al in a total amount of Ti and Al, and yavg is an average content ratio of C in a total amount of C and N. Some crystal grains composing the complex nitride or complex carbonitride layer have a cubic structure. In crystal grains having the cubic structure, the average crystal grain misorientaion is 1 degree or more; or 2 degrees or more, based on analysis of the polished surface perpendicular to a surface of the layer. A peak exists in 1-2 degrees of the average crystal grain misorientation in the frequency distribution of the average crystal grain misorientation and the area ratio.

摘要： A coated tool has a hard coating layer including a layer of a complex nitride or complex carbonitride expressed by (Ti1-xAlx)(CyN1-y). A periodic concentration variation is present in crystal grains of a complex nitride or complex carbonitride having a NaCl type face-centered cubic structure in the layer. The periodic concentration variation direction includes a direction at 30 degrees or less with respect to a surface of a tool body. An area percentage of a periodic concentration variation of Ti and Al is 40% or more. The concentration variation period is 1 to 10 nm. A difference between an average of local maximums and an average of local minimums of a periodically varying amount x of Al is 0.01 to 0.1. Fine crystal grains having a hexagonal structure with an average grain size of 0.01 to 0.3 μm are present at grain boundaries in 5% or less of the area.
