摘要： The invention relates to a soil-working device (1) for the agricultural preparation of earth, in particular for the planar cutting of earth, comprising a main body (2) and cutting elements (3) arranged on the latter, the main body (2) having a carrier face (7) and a sliding face (6), cutting elements (3) being arranged on the carrier face (7), and earth being able to slide off over the sliding face (6). According to the invention, to avoid smearing over a soil when working same, the sliding face (6) adjoins the carrier face (7) at an angle so that the distance of the sliding face from the earth increases away from the carrier face (7).

摘要： The invention relates to a cutting element (1) made of cemented carbide for an agricultural soil cultivation tool for cutting into the earth, comprising a top side (2) and a bottom side as well as a front side (3), a back side (4) opposite of the front side (3), and at least one lateral surface (5), wherein the top side (2) and bottom side are connected via the front side (3), back side (4), and the at least one lateral surface (5) and the front side (3) comprises a cutting region having multiple teeth, wherein at least one tooth is formed with a first flank (6) and a second flank (7). To achieve an efficient cutting into the earth with a complete cut through the weeds or herbaceous plants present in the earth, it is provided according to the invention that a profile line of the first flank (6) and a profile line of the second flank (7) have different lengths. In this manner, the weeds can be completely severed and thus killed, whereby a use of sprays for killing weeds is reduced and the environment can be protected to a considerable degree.

摘要： The invention relates to a process for coating an article (1), wherein a coating (2) having one or more coating layers (3, 4, 5) is applied to the article (1), wherein at least one coating layer (5) is formed essentially from aluminium, titanium and nitrogen, wherein the coating layer (5) has, at least in some regions, adjoining lamellae of different chemical composition and is deposited from a gas phase comprising at least one aluminium precursor and at least one titanium precursor. According to the invention, by setting a molar ratio of aluminium to titanium, the lamellae of different chemical composition are each formed with a cubic structure, it being possible for aluminium and titanium to be partly replaced by other metals and for nitrogen to be partly replaced by oxygen and/or carbon with retention of the cubic structure. The invention further relates to a correspondingly produced coating (2).

摘要： Cutting element made of cemented carbide for an agricultural soil cultivation tool for cutting into the earth, which includes a top side and a bottom side, a front side, a back side opposite of the front side, and at least one lateral surface. The top and bottom sides are connected via the front side, back side, and the at least one lateral surface. The front side includes a cutting region having multiple teeth, and at least one tooth is formed with a first flank and a second flank. To achieve an efficient cutting into the earth with a complete cut through the weeds or herbaceous plants present in the earth, a profile line of the first flank and a profile line of the second flank have different lengths. In this manner, weeds are completely severed and killed, whereby use of sprays for killing weeds is reduced to protect the environment.
