Abstract
1. Способ изготовления винта, имеющего головку, прилегающую к ней удерживающую секцию и функциональный наконечник, который имеет более высокую твердость, чем удерживающая секция, и изготовлен из закаленной низколегированной углеродистой стали по всех протяженности головки и удерживающей секции винта, при этом винт выдерживается в атмосфере, обогащенной углеродом и/или азотом, после его нагрева до температуры выше температуры аустенизации, причем в результате этого винт проходит стадию обогащения углеродом или азотом, которая ограничена его функциональным наконечником, после чего винт закаливается и отжигается и таким образом подвергается стадии упрочнения, отличающийся тем, что винт по всей поверхности его головки и удерживающей секции снабжают изолирующим слоем, действующим как диффузионный барьер, при этом функциональный наконечник подвергают кратковременной термообработке с последующим отжигом для того, чтобы увеличить его твердость, и в результате чего функциональный наконечник имеет, благодаря изолирующему слою, более высокое содержание углерода и/или азота, чем удерживающая секция.2. Способ по п. 1, отличающийся тем, что термообработку выполняют посредством индукции.3. Способ по п. 1, отличающийся тем, что термообработку выполняют посредством электронного луча.4. Способ по п. 1, отличающийся тем, что термообработку выполняют с помощью лазерного луча.5. Винт, отличающийся тем, что он изготовлен в соответствии со способом по любому из пп. 1-4.
