Abstract: A system for diagnosing an additive manufacturing device is provided. The system includes one or more processors, one or more non-transitory memory modules communicatively coupled to the one or more processors and storing machine-readable instructions. The machine-readable instructions, when executed, cause the one or more processors to: determine parameters associated with at least one subsystem of the additive manufacturing device, the parameters being related to a build generated by the additive manufacturing device; compare the parameters with threshold values; and determine a failure mode, among a plurality of failure modes, associated with a subsystem of the at least one subsystem of the additive manufacturing device based on the comparison of the parameters with the threshold values.

Abstract: At least one layer in a coating located on a surface of a substrate is a domain structure layer constituted of two or more domains different in composition and a thin layer located between the domains and being different in composition from each of the domains. The thin layer is located between any one domain and any another domain and in contact therewith. When the size of each of a plurality of first domains present in the domain structure layer is defined as a diameter of a virtual circumcircle in contact with each first domain, the average value of the size of each first domain is not smaller than 1 nm and not greater than 10 nm and a thickness of the thin layer in a direction of thickness of the domain structure layer is not less than 1 atomic layer and not more than 10 atomic layers.

Abstract: At least one layer in a coating located on a surface of a substrate is a domain structure layer constituted of two or more domains different in composition. The average value of the size of each of first domains, defined as the diameter of a virtual circumcircle in contact with each first domain, is 1 nm to 10 nm. The average value of the nearest neighbor distance of each first domain, defined as the length of the shortest straight line connecting the center of the circumcircle with the center of another circumcircle adjacent to the circumcircle, is 1 nm to 12 nm. 95% or more of the first domains has a size within ±25% of the average value of the size, and 95% or more of the first domains has a nearest neighbor distance within ±25% of the average value of the nearest neighbor distance.
