Abstract
1. Способ получения на деталях запорной арматуры защитного упрочняющего покрытия методом напыления порошкового материала, отличающийся тем, что напыление производят высокоскоростным газопламенным методом со скоростью перемещения горелки относительно обрабатываемой поверхности 0,5÷1,0 м/с, при этом напыление производят с поддержанием температуры поверхности 90±10°C путем создания дополнительного потока защитного газа в зоне напыления, а напыляемый порошковый материал может содержать аморфную фазу.2. Способ по п.1, отличающийся тем, что напыление производят на цилиндрическую поверхность детали таким образом, что траектория смещения горелки представляет собой винтовую поверхность, причем в каждом слое горелку перемещают с шагом h на один оборот детали, а в каждом последующем слое горелку смещают на величину s относительно предыдущего слоя таким образом, чтобы шаг h находился в следующем диапазоне h=1,8s÷2,2s.3. Способ по п.1, отличающийся тем, что напыление производят на сферическую поверхность детали таким образом, что траектория смещения горелки представляет собой винтовую поверхность, причем в каждом слое горелку перемещают с шагом h на один оборот детали, а в каждом последующем слое горелку смещают на величину s относительно предыдущего слоя таким образом, чтобы шаг h находился в следующем диапазоне h=1,8s÷2,2s.1. The method of obtaining on the parts of the stop valves of the reinforcing protective coating by the method of spraying powder material, characterized in that the spraying is performed by a high-speed gas-flame method with a speed of movement of the burner relative to the treated surface of 0.5 ÷ 1.0 m / s, while spraying is carried out while maintaining the temperature surface 90 ± 10 ° C by creating an additional flow of protective gas in the spray zone, and the sprayed powder material may contain an amorphous phase. 2. The method according to claim 1, characterized in that the spraying is carried out on the cylindrical surface of the part so that the path of the burner is a helical surface, and in each layer the burner is moved in increments of h by one revolution of the part, and in each subsequent layer, the burner is shifted by the value of s relative to the previous layer so that the step h is in the following range h = 1.8s ÷ 2.2s.3. The method according to claim 1, characterized in that the spraying is performed on the spherical surface of the part in such a way that the path of the burner is a helical surface, and in each layer the burner is moved in increments of h by one revolution of the part, and in each subsequent layer the torch is shifted by the value of s relative to the previous layer so that the step h is in the following range h = 1.8s ÷ 2.2s.
