Pump housing of two different sinterable materials

A method for producing a pump housing for a pump device, the method comprising:

• providing a first material;
• providing a further material that is different than the first material;
• forming a pump housing precursor, wherein a first subregion of the pump housing is formed from the first material and wherein two further subregions of the pump housing are formed from the further material and wherein the first subregion and the two further subregions alternate on an exterior circumference of the pump housing;
• and
• treating the pump housing precursor at a temperature of at least 300° C.

A method for producing a pump housing for a pump device, comprising the steps:

• providing a first material;
• providing a further material that is different than the first material;
• forming a pump housing precursor, wherein firstly at least two further subregions of the pump housing are formed from the further material and then a first subregion of the pump housing is formed from the first material and wherein a second further subregion of the pump housing is formed from the further material, and wherein the first subregion and the two further subregions alternate on an exterior circumference of the pump housing;
• and
• treating the pump housing precursor at a temperature of at least 300° C.

A housing at least partly surrounding an interior region and comprising a first end and a second end;

• wherein the housing has at least one first subregion and at least two further subregions, a material of the first subregion being different than a material of the two further subregions;
• wherein the first subregion comprises a ceramic to an extent of at least 61% by weight, based on the total mass of the first subregion;
• wherein the two further subregions comprises a metal content within a range from 40 to 90% by weight, based on the total mass of the two further subregions;
• wherein at least one part of the first subregion and at least one part of the two further subregions are connected to one another;
• and
• wherein the at least one further subregion is positioned at the first end or the second end of the interior region and wherein the at least one first subregion and the at least two further subregions alternate on an exterior circumference of the pump housing.
