Abstract
A manually guided implement having a tool and a brake mechanism for the tool. The brake mechanism includes a brake band that is looped about a brake drum. The brake band and the brake drum form abrasion partners that cooperate with one another during a braking process. At least one of the abrasion partners has a coating. The coating is provided with diamond particles that are embedded in a matrix that contains nickel. The coating is effected in a nickel bath in which the diamond particles are dispersed.
Claims18
A manually guided implement, comprising:
- a tool;
- a brake mechanism (10) for the tool, wherein said brake mechanism includes a brake band (13) that is looped about a brake drum (12), and wherein said brake band (13) and said brake drum (12) form abrasion partners that cooperate with one another during a braking process;
- and
- a coating (21) provided on at least one of said abrasion partners (13, 12), wherein said coating (21) includes diamond particles (22) that are embedded in a matrix (23), and wherein said matrix contains nickel.
A method of producing a brake mechanism (10) of a manually guided implement, including the steps of:
- providing a brake mechanism (10) that includes a brake drum (12) and a brake band (13), wherein said brake band (13) is looped about said brake drum (12), and wherein said brake band (13) and said brake drum (12) form abrasion partners that cooperate with one another during a braking process;
- and
- coating at least one of said abrasion partners (13, 12) in a nickel bath in which diamond particles (22) are dispersed.
