A wear resistant coating may comprise an amorphous metal comprising at least one refractory metal, at least two elements selected from periods 4, 5, 6, 9, and 10, and a metalloid. An amorphous metal may comprise at least one refractory metal, at least two elements selected from periods 4, 5, 6, 9, and 10, and a metalloid. A coating may comprise at least one refractory metal, at least two elements selected from periods 4, 5, 6, 9, and 10, and silicon. In some examples, the amorphous metal is TaWSi. In one example, the refractory metals may comprise Niobium, Molybdenum, Tantalum, Tungsten, Rhenium, or combinations thereof.

There is provided a head module including: a case; and a head provided with nozzles through which a liquid is jetted. The head includes: two first inlets through which the liquid flows into the head; and a first outlet through which the liquid flows out of the head. The case includes: a second inlet through which the liquid supplied from an outside flows into the case; two inflow-connecting ports communicating with the second inlet and connected to the two first inlets; an outflow-connecting port connected to the first outlet; and a second outlet communicating with the outflow-connecting port and through which the liquid flows out to the outside.

Provided is a method for manufacturing a liquid-ejecting head whereby in die slide injection molding it is possible to stably inject resin in secondary molding without damaging the shapes of parts that were formed in primary molding. In order for that, in the connecting section in which a convex section (H521) of a cover member (H121) is inserted into an opening (H500) of a liquid-supply member (H100), the closest distance (t2) to the opening in the area where secondary resin is injected is made larger than the gap (t1) between the opening (H500) and the convex section (H521). As a result, the resin is prevented from flowing into a liquid path (H501) during the secondary molding.

In an embodiment, a method of degassing ink in a fluid ejection device includes generating a localized nucleation site within an ejection chamber of a fluid ejection device. An air bubble is formed at the nucleation site, and the air bubble is prevented from venting into an ink supply slot using a bubble-impeding structure. The air bubble is vented through a nozzle associated with the ejection chamber and into the atmosphere.

A method for forming at thick film layer (30) of micro injecting device is disclosed in which a thin film layer (31') is formed on a substrate (1), a thick film layer (32') is formed on the thin film layer (31') without performing additional heat-treatment, and the thin film layer (31') and thick film layer (32') formed sequentially on the substrate are simultaneously heat-treated, to thereby complete a single thick film layer (30). The single thick film layer (30) is formed by a sequential coating process without being interfered by heat-treatment, thereby eliminating an isolating line. As a result, an overall durability of thick film layer (30) can be significantly enhanced.
