In certain example embodiments, a coated article includes respective layers including diamond-like carbon (DLC) and zirconium nitride before heat treatment (HT). During HT, the hydrogenated DLC acts as a fuel which upon combustion with oxygen produces carbon dioxide and / or water. The high temperature developed during this combustion heats the zirconium nitride to a temperature(s) well above the heat treating temperature, thereby causing the zirconium nitride to be transformed into a new post-HT layer including zirconium oxide that is scratch resistant and durable.

This application relates to a coated article including at least one infrared (IR) reflecting layer of a material such as silver or the like in a low-E coating. In certain embodiments, at least one layer of the coating is of or includes zirconium oxide (e.g., ZrO2) or zirconium silicon oxynitride (e.g., ZrSiOxNy). When a layer comprising zirconium oxide or zirconium silicon oxynitride is provided as the uppermost or overcoat layer of the coated article (e.g., over a silicon nitride based layer), this results in improved chemical and heat stability in certain example embodiments. Coated articles herein may be used in the context of insulating glass (IG) window units, vehicle windows, or in other suitable applications such as monolithic window applications, laminated windows, and / or the like.

The high temperature developed during this combustion heats the zirconium nitride to a temperature(s) well above the heat treating temperature, thereby causing the zirconium nitride to be transformed into a new post-HT layer including zirconium oxide that is very scratch resistant and durable.

The invention relates to a preparation method for a zirconium boride-based coating and relates to plating of a material by a boride. The method of in-situ synthesizing the zirconium boride-based coating comprises the steps of: preparing zirconium oxide / boron carbide / aluminum compound powder for thermal spraying; pre-treating a base material; and spraying the prepared zirconium oxide / boron carbide / aluminum compound powder for thermal spraying to the surface of the pre-treated base material by adopting a thermal spraying method so as to form the zirconium boride-based coating. The method provided by the invention overcomes the defects that in the prior art, the prepared zirconium boride-based coating is high in porosity, poor in uniformity, rough in tissue, low in toughness, small in thickness, poor in bonding force with a matrix, easy to crack and poor in thermal shock resistance; and the defects in the prior art that the preparation process is complicated, the process cost is high, the depositing efficiency is low, the cost of raw materials is high, the energy consumption is great, the efficiency is low, and the preparation method is not suitable for being applied to industrial production on a large scale.

The invention relates to a cutting tool comprising a main part and a multilayer coating applied thereon.
